Remove inappropriate memory context switch in shutdown_MultiFuncCall().

This was a thinko introduced in a patch from last February; it results
in memory leakage if an SRF is shut down before the actual end of query,
because subsequent code will be running in a longer-lived context than
it's expecting to be.
