drm: Unify and fix idr error handling
The error handling code w.r.t. idr usage looks inconsistent. In the case of drm_mode_object_get() and drm_ctxbitmap_next() the error handling is also incomplete. Unify the code to follow the same pattern always. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
