mac80211: fix PREQ processing and one small bug
commit 533866b12cce484994163b1e201778cbac4c04c5 upstream.
1st) a PREQ should only be processed, if it has the same SN and better
metric (instead of better or equal).
2nd) next_hop[ETH_ALEN] now actually used to buffer
mpath->next_hop->sta.addr for use out of lock.
