Thomas Weißschuh f52c8fba98 rfkill: return ENOTTY on invalid ioctl
For unknown ioctls the correct error is
ENOTTY "Inappropriate ioctl for device".

ENOSYS as returned before should only be used to
indicate that a syscall is not available at all.

[in theory this breaks userspace API, but it was discussed and
 researched, and nothing found relying on the current behaviour]
