drm/amd/ras: tolerate an unsupported MCA debug mode control

ras_mp1_set_debug_mode() reports -EOPNOTSUPP where the control does not
exist, an SR-IOV guest among them. Treating that as fatal fails
ras_core_sw_init() and takes RAS down on every VF.

Nothing else in the MP1 block depends on it, so carry on.
