drm: Fix race when checking for fb in the generic kms obj lookup
In my review of
commit 98f75de40e9d83c3a90d294b8fd25fa2874212a9

drm: add object property typ
I asked for a check to make sure that we never leak an fb from the
generic mode object lookup since those have completely different
lifetime rules. Rob added it, but outside of the idr mutex, which
means that our dereference of obj->type can already chase free'd
memory.
Somehow I didn't spot this, so fix this asap.
v2: Simplify the conditionals as suggested by Chris.
