avcodec/vp3: Remove always-false checks

Browse source 
The dimensions are only set at two places: theora_decode_header()
and vp3_decode_init(). These functions are called during init
and during dimension changes, but the latter is only supported
(and attempted) when frame threading is not active. This implies that
the dimensions of the various worker threads in
vp3_update_thread_context() always coincide, so that these checks
are dead and can be removed.

(These checks would of course need to be removed when support
for dimension changes during frame threading is implemented;
and in any case, a dimension change is not an error.)
