[Tarantool-patches] [PATCH v2 6/6] sql: remove unnecessary function initialization

[Mergen Imeev via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

After removing the SQL built-in functions from _func, the code used to
initialize these SQL built-in functions is no longer used and should be
removed.

Follow-up #6106
