Better fix for #11799

Receiving the SetWindowStyle command doesn't mean that any of the
existing caption strings have changed.

libmythtv: Kill a bogus warning about frequency range

If a frontend supports DiSEqC and is also a slave to a DVD-S master then
DVBChannel::CheckOptions incorrectly calls CheckFrequency which then
emits a bogus warning:
DVBChan(...) Warning: Your frequency setting (10773250) is out of range...

This patch fixes DVBChannel::CheckOptions to only call CheckFrequency if
the frontend doesn't have DiSEqC and isn't a slave.
