Revert "qcacld-3.0: Wait for sme_soc_set_dual_mac_config to get complete"

as it's not needed.

This wait-for-response causes a delay of around 200ms in
vdev_create as it's a blocking call.
As vdev_create happens after finding the peer device in case of
p2p, overall connection is delayed and connection time has
increased from 350ms to 600ms. This effects the
uses cases like WFD where applications have strict timing
constraints after finding the device.
