wlan: Support for GTK rekey offload

Earlier case supplicant was handling GTK rekeying
even when wlan suspended thus wlan host had to
come out from the sleep for GTK rekeying.
with this change, support for GTK offload has been added
so that firmware will take care of GTK rekey when
wlan is in suspend mode.
