hlsdemux: Fix checking adaptation_field_control field to parse pcr

Browse source 
The PCR_flag and PCR value is in adaptation_field, not in payload.
The MSB of adaptation_field_control is used as whether adaptation_
field is exist or not.

For the case(PCR in only adaptation_field without payload), we modify
checking condition about adaptation_field_control field.
