Due to commit
00e769d04c2c83029d6c71(btrfs-progs: Correct value printed
by assertions/BUG_ON/WARN_ON), which changed the assert_trace()
parameter, the condition passed to assert/WARN_ON/BUG_ON are logical
notted for backtrace enabled and disabled case.
Such behavior makes us easier to pass value wrong, and in fact it did
cause us to pass wrong condition for ASSERT().
Instead of passing different conditions for ASSERT/WARN_ON/BUG_ON()
manually, this patch will use ASSERT() to implement the resting
ASSERT/WARN_ON/BUG() for disable backtrace case, and use assert_trace()
to implement ASSERT() and BUG_ON(), to allow them to print correct
value.
Also, move WARN_ON() out of the ifdef branch, as it's completely the
same for both branches.

btrfs-progs: check: Fix false alert on generation mismatch for tree reloc tree
For fs with tree reloc tree(under balancing), lowmem mode will report
false alert like:
ERROR: extent[
62914560 4096] backref generation mismatch, wanted: <=9,
have: 13
This is because lowmem mode adds a more restrict check, to ensure
generation in fs tree won't be smaller than extent tree.
In fact such assumption is not right for tree reloc tree, so remove such
check.

ERROR: shared extent[

The problem is check_shared_block_backref() can't handle tree reloc

And still try to read out the tree block then seeking for the

The correct method for it is to check if it's tree reloc root.
In that case, we should check found the ROOT_ITEM of tree reloc tree in
root tree.

migrate_super_block() uses sectorsize to refer to the size of the

btrfs-progs: dev stats: add dev stats returncode option
Currently, `btrfs device stats` returns non-zero only when there was an
error getting the counter values. This is fine for when it gets run by a
user directly, but is a serious pain when trying to use it in a script or
for monitoring since you need to parse the (not at all machine friendly)
output to check the counter values.
This patch adds an option ('-s') which causes `btrfs device stats`
to set bit 6 in the return code if any of the counters are non-zero.
This greatly simplifies checking from a script or monitoring software if
any errors have been recorded. In the event that this switch is passed
and an error occurs reading the stats, the return code will have bit
0 set (so if there are errors reading counters, and the counters which
were read were non-zero, the return value will be 65).

Simplifying the logic of fixing.
Calling fixup_extent_ref() after encountering every error causes
more error messages after the extent is fixed. In case of multiple errors,
this is confusing because the error message is displayed after the fix
message and it works on stale data. It is best to show all errors and
then fix the extents.
