vl_rbsp_fillbits may fill less than 32 bits if it removes emulation prevention bytes, but will fill at least 16 bits. We need to call it twice when reading more than 16 bits. This fixes parsing H264 SPS packed header in va frontend when emulation prevention bytes are at position where 32 bit values are read.
