usermodehelper: split remaining calls to call_usermodehelper_fns()
These are the only users of call_usermodehelper_fns(). This function suffers from not being able to determine if the cleanup is called. Even if in this places the cleanup pointer is NULL, convert them to use the separate call_usermodehelper_setup() + call_usermodehelper_exec() functions so we can remove the _fns variant.
