[Tarantool-patches] [PATCH v21 2/6] box/func: module_reload -- drop redundant argument

[Cyrill Gorcunov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

The only purpose of the module argument is to
notify the caller that the module doesn't exist.
Lets simplify the code and drop this argument.

Part-of #4642
