From: Brian Foster <bfoster@xxxxxxxxxx>
commit 826f7e34130a4ce756138540170cbe935c537a47 upstream.
The xfs_log_item flags were converted to atomic bitops as of commit
22525c17ed ("xfs: log item flags are racy"). The assert check for
AIL presence in xfs_buf_item_relse() still uses the old value based
check. This likely went unnoticed as XFS_LI_IN_AIL evaluates to 0
and causes the assert to unconditionally pass. Fix up the check.
