avcodec: vdpau: do not rely on AVCodecContext->refs for HEVC

lavc doesn't set this value to a meaningful value. Only the H264 codec
has this value properly set.

Bogus log introduced in 7905bf1eba6b38d8456f414478cfe6809a07614f.
Before the code would rely on refs which is one and add 5 arbitrary pictures
which was OK until HEVC and VP9 were introduced.
