Richard Sanger 171c3b1511 net: packetmmap: fix only tx timestamp on request 
The packetmmap tx ring should only return timestamps if requested via
setsockopt PACKET_TIMESTAMP, as documented. This allows compatibility
with non-timestamp aware user-space code which checks
tp_status == TP_STATUS_AVAILABLE; not expecting additional timestamp
flags to be set in tp_status.

Fixes: b9c32fb271 ("packet: if hw/sw ts enabled in rx/tx ring, report which ts we got")
