[XFS] Fix racy access to pb_flags. pagebuf_rele() modified pb_flags after
the pagebuf had been unlocked if the buffer was delwri. At high load, this could result in a race when the superblock was being synced that would result the flags being incorrect and the iodone functions being executed incorrectly. This then leads to iclog callback failures or AIL list corruptions resulting in filesystem shutdowns.
