qcacld-3.0: Convert wlan_hdd_cfg80211.c to unified logging [6/6]

Currently the HDD code uses a variety of logging APIs.  In qcacld-3.0
HDD should converge on a unified set of logging APIs.  Update
wlan_hdd_cfg80211.c to use the unified set of APIs.  Since there are a
large number of changes in this file, perform the conversion in
phases.

For phase 6 set the HDD_DISALLOW_LEGACY_HDDLOG flag so that no future
changes can introduce new instances of legacy logging.
