airo: fix setting zero length WEP key
Patch prevents call set_wep_key() with zero key length. That fix long
standing regression since commit c0380693520b1a1e4f756799a0edc379378b462a
"airo: clean up WEP key operations". Additionally print call trace when
someone will try to use improper parameters, and remove key.len = 0
assignment, because it is in not possible code path.
