Revert "Upcall/gfapi: Return ENOTSUP when upcall feature is disabled"

This reverts commit b68f671b2b8a0aafef8f98145aee7044edaa907d from
http://review.gluster.org/11196 . The change depends on modifications to
the cluster xlators, but these are still partially under review.

Dropping this change now, it causes regression tests to fail.
