[PATCH 06/19] P2P: Make more precise device timestamping

From: Andrei Otcheretianski <andrei.otcheretianski at intel.com>

When adding group clients to the p2p device list, use the driver provided
BSS entry timestamp instead of current time. Otherwise, the time comparison
which is made in p2p_add_device doesn't make sense.
