[PATCH 3.12 043/235] xfs: set AGI buffer type in xlog_recover_clear_agi_bucket

3.12-stable review patch. If anyone has any objections, please let me know.


commit 6b10b23ca94451fae153a5cc8d62fd721bec2019 upstream.

xlog_recover_clear_agi_bucket didn't set the
type to XFS_BLFT_AGI_BUF, so we got a warning during log
replay (or an ASSERT on a debug build).

XFS (md0): Unknown buffer type 0!
XFS (md0): _xfs_buf_ioapply: no ops on block 0xaea8802/0x1

Fix this, as was done in f19b872b for 2 other locations
with the same problem.
