qcacld-3.0: Fix the regression issue for pktlog failure with ROME module

The pktlog will fail with ROME module due to the change IDs:
I24776caa3b78ec38d94421f243ec72d81ee3102d
Ifb70ac0993f2402201f88758845f730cf677b1a0

Define new macro PKTLOG_LEGACY for HELIUM/ROME to avoid the ROME PKTLOG
failure.
