Unaligned access fixes
The first problem is that these SETGET macros lose typing information,
and therefore can't see the 'packed' attribute and therefore take
unaligned access SIGBUS signals on sparc64 when trying to derefernce
the member.
The next problem is a similar issue in btrfs_name_hash(). This gets
passed things like &key.offset which is a member of a packed
structure, losing this packed'ness information btrfs_name_hash()
performs a potentially unaligned memory access, again resulting in a
SIGBUS.

Fixes for the converter
Hello,
This patch fixes two newly found bugs in the converter. The important
one is in create_ext2_image, sub-volume root directory's size not

a small bug in xattr support codes. In addition to the fixes, this
patch moves the 'if mounted' check to main() function.
