gccrs: Fix ICE in check for unused global variables
Calling get variable expression will return an expression but we are
checking for unused decls so lets actually pass the decl.
Addresses #2188
gcc/rust/ChangeLog:
* checks/lints/rust-lint-unused-var.cc (UnusedVariables::Lint): use the decl not the expr
