kernel: drm/sched: Fix potential double free in drm_sched_job_add_resv_dependencies

A flaw was found in the kernel subsystem handling of the DRM scheduler. Under certain error conditions, the function drmschedjobadddependency consumes a fence reference and then later erroneously attempts to free it again double free. This may lead to memory corruption and, in some configurations...
