xfs: inode unlink does not set AGI buffer type
commit f19b872b086711bb4b22c3a0f52f16aa920bcc61 upstream. This leads to log recovery throwing errors like: XFS (md0): Mounting V5 Filesystem XFS (md0): Starting recovery (logdev: internal) XFS (md0): Unknown buffer type 0! XFS (md0): _xfs_buf_ioapply: no ops on block 0xaea8802/0x1 ffff8800ffc53800: 58 41 47 49 ..... Which is the AGI buffer magic number. Ensure that we set the type appropriately in both unlink list addition and removal.
