PPS scaling list inferring fix

Description

Suggestion to fix SHM decoder on PPS scaling list inferring process.

When pps_infer_scaling_list_flag is equal to 1 in EL PPS, the current decoder makes MD5sum mismatch. I think it is due to the wrong if-branch condition of the decoder.

Attached zip includes a sample bitstream to reproduce the bug and a suggested fix.

The sample bitstream has two layers. The BL PPS has pps_scaling_list_data_present_flag equal to 1, and the EL PPS has pps_infer_scaling_list_flag equal to 1.

I confirmed MD5sum match by SHM-dev decoder (rev.1008) with the fix patch.
