media: friio-fe: get rid of set_property()

commit b2c41ca9632e686e79f6c9db9c5f75666d37926e upstream

This callback is not actually doing anything but making it to
return an error depending on the DTV frontend command. Well,
that could break userspace for no good reason, and, if needed,
should be implemented, instead, at set_frontend() callback.

So, get rid of it.
