[dev.regabi] cmd/compile: remove race-y check in Name.Canonical

The backend doesn't synchronize compilation of functions with their
enclosed function literals, so it's not safe to double-check that
IsClosureVar isn't set on the underlying Name. Plenty of frontend
stuff would blow-up if this was wrong anyway, so it should be fine to
omit.
