[Tarantool-patches] [PATCH] Fix luacheck warning W122 in extra/dist/tarantoolctl.in

[Artem Starshov <artemreyt@tarantool.org>]

Changed passing global variable arg to function find_instance_name(arg) instead of passing arg[0] and arg[2] separately.
And removed exception in .luacheckrc for file /extra/dist/tarantoolctl.in.

This change only solves linter warning, nothing else
