drm/i915/guc: Prepare for error propagation
Currently guc_mmio_reg_add() relies on having enough memory available in
the array to add a new slot. It uses
`GEM_BUG_ON(count >= regset->size);` to protect going above the
threshold.
In order to allow guc_mmio_reg_add() to handle the memory allocation by
itself, it must return an error in case of failures. Adjust return code
so this error can be propagated to the callers of guc_mmio_reg_add() and
guc_mmio_regset_init().
No intended change in behavior.
