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. Change-Id: If5ae4a519c9c6312cdb2e2a31acce4b1901f9442 BUG: 1231132 Signed-off-by: Soumya Koduri <skoduri@redhat.com> Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/11452
