[XFS] Fix sparse warning in xlog_recover_do_efd_trans.
Sparse trips over the locking order in xlog_recover_do_efd_trans() when
xfs_trans_delete_ail() drops the ail lock. Because the unlock is
conditional, we need to either annotate with a "fake unlock" or change the
structure of the code so sparse thinks the function always unlocks.
Reordering the code makes it simpler, so do that.
