mac80211: initialize sta->last_rx in sta_info_alloc

BugLink: http://bugs.launchpad.net/bugs/761134

commit 8bc8aecdc5e26cfda12dbd6867af4aa67836da6a upstream.

This field is used to determine the inactivity time. When in AP mode,
hostapd uses it for kicking out inactive clients after a while. Without this
patch, hostapd immediately deauthenticates a new client if it checks the
inactivity time before the client sends its first data frame.
