drm/amdkfd: Fix potential deallocation of previously deallocated memory.
Pointer mqd_mem_obj can be deallocated in kfd_gtt_sa_allocate().
The function then returns non-zero value, which causes the second deallocation.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: d1f8f0d17d40 ("drm/amdkfd: Move non-sdma mqd allocation out of init_mqd")
