qcacld-2.0: Do not handle regdomain notifier after cfg80211 suspend
Currently, kernel invoke the regdomain notifier to host driver
using registered callback. If kernel call this callback after
cfg80211 aka system suspend, Then because of race condition host
might send the PDEV SET REGDOMAIN/PARAM to fwr after WOW ENABLE
cmd which is not correct cmd sequence.
