Revert "gfs2: Force withdraw to replay journals and wait for it to finish" (5/6)

The current withdraw code duplicates the journal recovery code gfs2
already has for dealing with node failures, and it does so poorly.  That
code was added because when releasing a lockspace, we didn't have a way
to indicate that the lockspace needs recovery.  We now do have this
feature, so the current withdraw code can be removed almost entirely.
This is one of several steps towards that.

journals and wait for it to finish").
