drm/ttm: Avoid calling drm_ht_remove from atomic context

On recent kernels, calling drm_ht_remove triggers a might_sleep() warning
from within vfree(). So avoid calling it from atomic context. The use-cases
we fix here are both from destructors so there should be no concurrent
use of the hash tables.
