Would allow earlier faults instead of having corrupted cmdstream.
This was already done to Freedreno long ago in:
04aff7e4 "freedreno: make cmdstream bo's read-only to GPU"
Since private memory should be GPU writable it is now allocated
separately, instead of suballocation from now read-only cmdstream.
