There are 3 functions reporting the same log, which is not straight
forward enough for users:
 - hevc_parse_slice_header()
 - ff_hevc_decode_nal_pps()
 - hls_slice_header()

Provide detailed logs to distinguish from "out of range PPS id" and
"empty pps_list[pps_id]".

PPS id out of range: 0
PPS id out of range or empty pps_list[0]: 0

Since 0 is within the range of pps_id, it's more clear that there is
an invalid pps_list.
