v4l2slvp8dec: Flip the meaning of segment_feature_mode
...
In section 9.3.4 a), segment_feature_mode have 0 for absolute and 1 for delta,
while in 19.2, it says the opposite. But the reference code, which usually
rules over the text state that 1 means absolute:
if (hdr->update_data)
{
hdr->abs = bool_get_bit(bool);
And uses it with that meaning to decide weither to override the existing value
or just add the detla. This fixes multiple decoding issues.

v4l2slvp8dec: Ensure width/height is always set
...
Our parser strictly read the bitstream. As it's known from DXVA that always
having a valid width/height might be needed, use the cached width/height
instead of the value from the parser. This didn't impact Hantro driver.
