[PATCH 2/2] drm/xe: Fix exec queue unwind on hw engine group add failure

[Shuicheng Lin <shuicheng.lin@intel.com>]

When xe_hw_engine_group_add_exec_queue() fails in
xe_exec_queue_create_ioctl(), to undo xe_exec_queue_group_add()
and xe_vm_add_compute_exec_queue(), the code should unwind through
kill_exec_queue rather than directly dropping the queue reference.

v2: correct the jump label. (Matt)
