nouveau/gsp/r535: Fix a NULL vs error pointer bug
The r535_gsp_cmdq_get() function returns error pointers but this code
checks for NULL. Also we need to propagate the error pointer back to
the callers in r535_gsp_rpc_get(). Returning NULL will lead to a NULL
pointer dereference.
Fixes: 176fdcbddfd2 ("drm/nouveau/gsp/r535: add support for booting GSP-RM")
