xfs: move inode shrinker unregister even earlier

I missed Dave Chinner's second revision of this change, and pushed
his first version out to the repository instead.

	commit a476c59ebb279d738718edc0e3fb76aab3687114
	Author: Dave Chinner <dchinner@redhat.com>

This commit compensates for that by moving a block of code up a bit
further, with a result that matches the the effect of Dave's second
version.

Dave's first version was:
