Sparse reports a warning at xfs_ail_check()

warning: context imbalance in xfs_ail_check() - unexpected unlock

The root cause is the missing annotation at xfs_ail_check()

Add the missing __must_hold(&ailp->ail_lock) annotation

Seems reasonable, though I'm wondering if this is a treewide change you
seek to apply yourself, or merely a large patch series to merge through
the individual subsystem maintainers?
