[tarantool-patches] [PATCH] sql: remove temporary box_iterator_key_def

[Kirill Yukhin <kyukhin@tarantool.org>]

It is possible to extract key_def from iterator directly
in SQL FE. So, no need in any temporary API hacks anymore.
The patch removes this API function and replaces its calls
w/ direct field access in SQL FE.

Closes #2425
