Btrfs-progs: Do not force mixed block group creation unless '-M' option is specified
When creating small Btrfs filesystem instances (i.e. filesystem size <= 1GiB),
mkfs.btrfs fails if both sectorsize and nodesize are specified on the command
line and sectorsize != nodesize, since mixed block groups involves both data
and metadata blocks sharing the same block group. This is an incorrect behavior
when '-M' option isn't specified on the command line.
This commit makes optional the creation of mixed block groups i.e. Mixed block
groups are created only when -M option is specified on the command line.
Since we now allow small filesystem instances with sectorsize != nodesize to
be created, we can end up in the following situation,

Reason:
I run above test in a NFS mountpoint, it don't have enouth space to write
all superblock to image file, and don't support sparse file.
So write_dev_supers() failed in writing sb and output above message.
It takes me quite of time to know what happened, we can save these time
by output exact information in write-sb-fail case.
After patch:
# ./fsck-tests.sh

WARNING: Write sb failed: File too large
disk-io.c:1492: write_all_supers: Assertion `ret` failed.

btrfs-progs: Increase running state's priority in stat output
Anthony Plack <anthony@plack.net> reported a output bug in maillist:
title: btrfs-progs SCRUB reporting aborted but still running - minor
btrfs scrub status report it was aborted but still runs to completion.

Reason:
When scrub multi-device simultaneously, if some device canceled,
and some device is still running, cancel state have higher priority to
be outputed in global report.
So we can see "scrub aborted" in status line, with running-time keeps
increased.
Fix:
We can increase running state's priority in output, if there is
some device in scrub state, we output running state instead of
cancelled state.

btrfs-progs: fix is_block_device() return checks
it was highlighted to me is_block_device(), returns
1 if the file is a block device,
< 0 in case of an error (eg: file not found)
0 otherwise
This patch makes proper return checks at all the places
where is_block_device() is used. Thanks to Goffredo.
