mac80211: Clear beacon_int in ieee80211_do_stop
This fixes stale beacon-int values that would keep a netdev
from going up.
To reproduce:
Create two VAP on one radio.
vap1 has beacon-int 100, start it.
vap2 has beacon-int 240, start it (and it will fail
because beacon-int mismatch).
reconfigure vap2 to have beacon-int 100 and start it.
It will fail because the stale beacon-int 240 will be used
in the ifup path and hostapd never gets a chance to set the
new beacon interval.
