No need for the masking here, as xfs_iflush simply ignores SYNC_TRYLOCK.

So for the !wait case we entirely ignore the return value? We should
at least check for an I/O error here I think. Also in this context
the requeue label name doesn't fit too well, even if it's the same
action as the requeue.
