wlan: Change the behavior of isLoadUnloadInProgres

Some APIs (wlan_hdd_linux_reg_notifier) can be allowed to execute if
driver load is in progress but should be blocked if driver unload is in
progress, to be able to cater to the needs of such APIs change
isLoadUnloadInProgress so that it can distinguish between driver load
and unload.
