VC1: Fix intensity compensation performance regression
Fix https://trac.ffmpeg.org/ticket/3204
The problem was that intensity compensation was always used once it was
encountered. This is because v->next_use_ic was never set back to zero.
To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic.
This improved (restored) performance by 85% when decoding
