drm/sched: One function call less in drm_sched_init() after error det…

…ection The kfree() function was called in one case by the drm_sched_init() function during error handling even if the passed data structure member contained a null pointer. This issue was detected by using the Coccinelle software. Thus adjust a jump target.
