The variable should be cleared regardless of whether there's a peer associated with the key or not. This fixes case when user first associates with 2 WEP keys and then disconnects and connects with 1 WEP key. This resulted in WEP key count being 2 in the driver leading to default keyidx fixup failure. Signed-off-by: Michal Kazior <redacted>
