qcacld-3.0: use hwtstamp to pass HW timestamp info

Based on the current codes, Host driver use "tstamp" of skb buffer
structure to store HW timestamp info. But this parameter is designed
for SW timestamp. If host driver fill the value to "tstamp", it will
affect other functions, for example, NTP, PING etc.
The host driver use "hwtstamp" of skb buffer structure to store
the HW timestamp info now.
