lavc/vp9: fix reference frame dimensions check for SINGLE_REFERENCE mode
With the description in frame size with refs semantics (SPEC 7.2.5),
it is a requirement of bitstream conformance that for at least one
reference frame has the valid dimensions.
Modify the check to make sure the decoder works well in SINGLE_REFERENCE
mode that not all reference frames have valid dimensions.
Check and error out if invalid reference frame is used in inter_recon.
One of the failure case is a 480x272 inter frame (SINGLE_REFERENCE mode)
with following reference pool:
0. 960x544 LAST valid
1. 1920x1088 GOLDEN invalid, but not used in single reference mode
2. 1920x1088 ALTREF invalid, but not used in single reference mode
3~7 ... Unused
Identical logic in libvpx:
