/*! @brief Helper function to check for an interface.

    Most of the other check_dispatcher_*_interface functions use call this helper function, that
    does most of the real work. It generates a usable userptr containing the client_t structure of
    the calling process. If the calling syscall label enum is outside of given range,  DISPATCH_PASS
    is returned.

    @param m The recieved message structure.
    @param userptr Output userptr containing corresponding client, to be passed into generated
                   interface dispatcher function.
    @param labelMin The minimum syscall label to accept. 
    @param labelMax The maximum syscall label to accept.
