[PATCH] ieee80211: Workaround malformed 802.11 frames from AP

Stop processing further but return success when we receive a malformed
packet from the AP. We need this patch to workaround some AP bugs. For
example, the beacon frames from the Orinoco AP1000 contains an IE (value
= 128) with length equals to 8 but the actual frame length is only 7.
