xfs: simplify xchk_parent_validate

This function is unnecessarily long because it contains code to
revalidate a dotdot entry after cycling locks to try to confirm a
subdirectory parent pointer.  Shorten the codebase by making the
parent's lookup call do double duty as the revalidation code.

This weakeans the efficacy of this scrub function temporarily, but the
next patch will resolve this as part of fixing an unhandled race that is
the result of the VFS rename locking model not working the way Darrick
thought it did.

Rename this stupid 'dnum' variable too.
