Subject: [PATCH] linuxdvb: remove full mux rx mode

There is currently no use for this feature in TVH, it was only ever added as
a means of getting internal table filtering going and with the idea of some
caching feature that's never materialised. However enabling on low performance
devices can often cause problems, so until there is a genuine use I'm removing
confusion.
