drm/amdgpu: fix NULL pointer dereference for Renoir
Commit c1cf79ca5ced46 ("drm/amdgpu: use IP discovery table for renoir")
introduced a NULL pointer dereference when booting with
amdgpu.discovery=0, because it removed the call of vega10_reg_base_init()
for that case.
Fix this by calling that funcion if amdgpu_discovery == 0 in addition to
the case that amdgpu_discovery_reg_base_init() failed.
Fixes: c1cf79ca5ced46 ("drm/amdgpu: use IP discovery table for renoir")
