drm/i915/guc: Replace check for golden context size
In the other places in this function, guc->ads_map is being protected
from access when it's not yet set. However the last check is actually
about guc->ads_golden_ctxt_size been set before. These checks should
always match as the size is initialized on the first call to
guc_prep_golden_context(), but it's clearer if we have a single return
and check for guc->ads_golden_ctxt_size.
This is just a readability improvement, no change in behavior.
