drm/amdkfd: Fix kfd_process_device_init_vm error handling
Should only destroy the ib_mem and let process cleanup worker to free
the outstanding BOs. Reset the pointer in pdd->qpd structure, to avoid
NULL pointer access in process destroy worker.
BUG: kernel NULL pointer dereference, address: 0000000000000010
