If the trylock fails and the buffer is pinned and stale, the resulting xfs_log_force() can lead to lock recursion on the ailp xa_lock. Call __xfs_buf_trylock() to attempt the buf lock with xa_lock held, but to avoid the log force. If the trylock had raced with the buffer being pinned, return XFS_ITEM_PINNED such that xfsaild will pend up a log force on the next scan.
