gigaset: return -ENOTTY for unimplemented functions

A number of functions in the usb_gigaset module will return -EINVAL if
CONFIG_GIGASET_UNDOCREQ is not set. Make these return -ENOTTY as it's
more specific and it might make it easier to see (from userspace) why
these functions actually fail.

Impact: some error return codes changed
