qcacld-3.0: Convert wlan_hdd_main.c to unified logging [7/7]
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_main.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 7 set the HDD_DISALLOW_LEGACY_HDDLOG flag so that no future
changes can introduce new instances of legacy logging.
