qcacld-3.0: Increase hdd disconnect wait time

wlan_hdd_disconnect wait time is 5 second.
WMA_VDEV_STOP_REQUEST_TIMEOUT is 6 second.There have 1 sec gap.
Which means if timeout happend, wlan_hdd_disconnect will exit before
wma_vdev_resp_timer is invoked. wma_vdev_resp_timer will trigger SME
to invoke callback hdd_dis_connect_handler to release vdev obj ref
count.

If unload driver during the time gap, vdev cannot destory
successfully because hdd_dis_connect_handler haven't be called.

rmmod will wait for wlan_hdd_disconnect exiting then unload driver.
So increase hdd disconnect wait time. Make sure wlan_hdd_disconnect
exit after lower layer timeout and hdd disconnect handler be called.
