qcacld-3.0: Avoid all module logging onto kmsg during driver load

This is qcacld-2.0 to qcacld-3.0 propagation

Avoid logging of all module logs into kmsg during the driver load
phase. All module log level is set much before setting of the
flag that indicates whether multicast logging is enabled or not.
Because of this all module log levels are getting printed for a
brief duration in kmsg during driver load. Fix the same by
setting the multicast flag appropriately so that when multicast
logging is enabled, all the logs are multicast to user space
and only the error and fatal messages continue to get logged in
the kmsg.
