V4L/DVB (7126): tuner: move tuner type ID check to simple_tuner_attach
Move tuner type ID check from tuner-core::set_type to simple_tuner_attach.
Since tuner-core forwards all attach requests to tuner-simple as the
default case, unless a specific attach function is specified in
set_type, this change is an appropriate cleanup.
