Subject: YJIT: Fix crash when yielding keyword arguments

Previously, the code for dropping surplus arguments when yielding
into blocks erroneously attempted to drop keyword arguments when there
is in fact no surplus arguments. Fix the condition and test that
supplying the exact number of keyword arguments as require compiles
without fallback.
