[Tarantool-patches] [PATCH] sql: fix assertion fail when selecting from _vfunc

This patch already has LGTM from Vlad. However, I moved changes to
the 2.3.2 upgrade, as long as the patch was no longer valid.

The assertion mentioned #4666 fails because it was forgotten to update
_vfunc format along with _func in 2.2.1. This leads to bad allocation
of vdbe cursor and setting wrong memory to 0.

Closes #4666
