qcacld-3.0: Do not send replay counter for CCKM

Browse Source 
Do not include replay counter attribute when roaming
is done for CCKM authentication type. For 11R and CCKM
roaming, the re-association frame carries additional
IE's which help cut down the Key exchange post
association. Hence there would be no EAPOL exchange
and hence it is not needed to include the replay
counter attribute to the supplicant after roaming.
