[PATCH] mac80211: fix printk warning on 64-bit

[Johannes Berg]

My AID message patch introduced a warning on 64-bit machines because ~
extends to unsigned long:

| net/mac80211/ieee80211_sta.c: In function =E2=80=98ieee80211_rx_mgmt_=
assoc_resp=E2=80=99:
| net/mac80211/ieee80211_sta.c:1187: warning: format =E2=80=98%d=E2=80=99=
 expects type =E2=80=98int=E2=80=99, but argument 7 has type =E2=80=98l=
ong unsigned int=E2=80=99

This fixes it by explicitly casting the result to u16 (which 'aid' is).
