qcacld-3.0: Fix cds_is_load_unload_in_progress API

cds_is_load_unload_in_progress is checking for both driver
load AND unload states. This is leading to all external threads
still enter in driver when driver has already started unload
clean up process. Fix this API to check either load OR unload
in progress driver states.
