drm/msm/adreno: fix userspace-triggered crash on a2xx-a4xx
Before a5xx Adreno driver will not try fetching UBWC params (because
those generations didn't support UBWC anyway), however it's still
possible to query UBWC-related params from the userspace, triggering
possible NULL pointer dereference. Check for UBWC config in
adreno_get_param() and return sane defaults if there is none.
Fixes: a452510aad53 ("drm/msm/adreno: Switch to the common UBWC config struct")
