Write_buf/write_index use confusing boolean values for return,
meaning that it's hard to tell what the correct error return is
supposed to be. Convert them to return zero on success or a
negative errno otherwise so that it's clear what the error case is.

Looks like this patch broke metadumps on some corrupted filesystems.
This is a legacy filesystem that has zeroes overwriting the
SB/AGF/AGI on AG 1/2/3:
# xfs_metadump -wgo /dev/sda8 myfile.metadata
xfs_agf_read_verify: XFS_CORRUPTION_ERROR
xfs_metadump: cannot init perag data (117). Continuing anyway.
Copied 64 of 64 inodes (0 of 4 AGs) xfs_agf_write_verify: XF
S_CORRUPTION_ERROR
write_buf: write verifer failed on bno 0x1100919/0x200
(no output)
Where did it crash? Can you post the stack trace from gdb? Even
better, can you send a patch to fix the problem? ;)
Cheers,
Dave.
No crash, just exits without performing the dump.
--Mark.
