qcacld-3.0: Increase the NDP_END wait timeout to 4 seconds

Currently, host driver expects NDP_END indication from firmware
within 2 seconds after sending request to firmware. Driver shall
timeout and cleanup the corresponding NDP entry if no response is
received within 2 seconds. But firmware may take upto 2.5 seconds
to exhaust the NDP_END frame retries.
So, increase the timeout to 4 seconds to accommodate these retries
and to be inline with current NAN_DISABLE timeout.
