gccrs: Do not assert insertion result

We might have some duplicated name in some pattern and we should
therefore not assert the non duplication of identifiers.

gcc/rust/ChangeLog:

	* resolve/rust-late-name-resolver-2.0.cc (Late::visit): Remove
	assertion and explicitely tells why we ignore the insertion result.
