Subject: [PATCH 4.9 02/51] Revert "bsg-lib: dont free job in bsg_prepare_job"

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit eb4375e1969c48d454998b2a284c2e6a5dc9eb68 which was
commit f507b54dccfd8000c517d740bc45f20c74532d18 upstream.

Ben reports:
	That function doesn't exist here (it was introduced in 4.13).
	Instead, this backport has modified bsg_create_job(), creating a
	leak.  Please revert this on the 3.18, 4.4 and 4.9 stable
	branches.

So I'm dropping it from here.
