qcacld-3.0: Fix for scan passive dwell time

Prensently for initial scan and roam passive scan dwell time,
the same ini CFG_PASSIVE_MAX_CHANNEL_TIME is used. This will
cause initial scan to have the roam passive scan value.

Decouple passive scan and roam passive scan ini parameter by
adding new ini param for roaming
