[RISCV] Remove dead code from doPeepholeMaskedRVV [nfc]

This is after lowering of undef to IMPLICIT_DEF, so the condition is always false.  Rather than fixing the intent (which was to match implicit_def per the comment), just delete it.  We're in the process of migrating away from the TA pseudos, so using _TA more often is fine.
