submodule: port submodule subcommand 'deinit' from shell to C
The same mechanism is used even for porting this submodule subcommand, as used in the ported subcommands till now. The function cmd_deinit in split up after porting into four functions: module_deinit(), for_each_listed_submodule(), deinit_submodule() and deinit_submodule_cb().
