[PATCH] af9013 Extended monitoring in set_frontend.

[Malcolm Priestley <tvboxspy@gmail.com>]

Try this patch, it should stop start up corruption on the same frontend.

It is a missing section of code that checks the frontend is ready to go.

However, it will not stop corruptions on frontend A.

af9013 Extended monitoring in set_front.
