The PPS should be used instead of the SPS to get the current picture's
dimensions. Using the SPS can cause issues if the resolution changes
mid-sequence. In particular, it was leading to invalid memory accesses
if the resolution decreased.
Patch replaces sps->{width,height} with pps->{width,height}. It also
removes sps->{width,height}, as these are no longer used anywhere.
