qcacld-3.0: Move wma log flush event registration to wma_open

wma flush log event handler is registered during wma_start which
is not done until interface is up. This leads to excessive logging
from WMI layer because event handler is not registered. Move wma
flush log event handler registration to wma_open such that after
driver load FW log flush events are handled properly.
