patches for if_iwi and wlan for WEP mode

[Adrian Chadd]

Hi,

I'd rather you file a PR first describing what you just did, then
commit the fix and close the PR.

Since you've found a problem, it sounds like a great reason to open a
Problem Report. :)

You can then link the commit against the PR so they reference each other.

I've been doing it for my ath/net80211 bugfixes, no matter how quickly
I find/fix the bug.
