[COMMITTED 039/146] gccrs: Fix FnParam pattern location ternary logic

[arthur . cohen]

From: Pierre-Emmanuel Patry <pierre-emmanuel.pa...@embecosm.com>

Condition was inverted, we should retrieve the locus only if we have a
pattern.

gcc/rust/ChangeLog:

        * typecheck/rust-tyty-call.cc (TypeCheckCallExpr::visit): Do not
        get a reference if the pattern does not exist.
        (TypeCheckMethodCallExpr::check): Likewise.
