[Patch] bttv: Enable radio if the card description has no radio flag but the tuner has FM

[Nils Kassube]

Some bttv cards (e.g. card=24) have a tuner which can receive FM radio 
but the card description doesn't have the has_radio flag set, because 
the description is used for cards with and without FM capability. The 
function bttv_init_tuner can detect the tuner either automatically or by 
insmod option. However the original code only partly uses the detected 
tuner capabilities. While the radio device node is created, the device 
is not usable due to the wrong mode_mask. This patch uses the has_radio 
flag from the detected tuner instead of the card description.
