qcacld-3.0: Register hdd callbacks before event registration

Browse source 
Presently the hdd callbacks registration for the events that
need to update data to HDD/SME/LIM from WMA are done after the
event registration is done. During the modules closing, the
callbacks are unregistered first and then the events gets
unregistered.

Move the callback registration before htc_start happens during
modules starting and similarly during modules stop, move the
deregistration of the callbacks after htc_stop.
