gccrs: nr2.0: default-visitor: Conditionally visit type in self parameters.

This could trigger an assertions as `get_type` on `SelfParam` asserts that
the self param does have a given type, which is not always the case.

gcc/rust/ChangeLog:

	* resolve/rust-default-resolver.cc (DefaultResolver::visit): Do not
	visit self's type if it does not have one.
