qcacld-3.0: send correct status code when WEP AUTH fail

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

With invalid WEP password, some APs reply AUTH frame 4 with
invalid seqNumber. This AUTH frame will be dropped by driver,
then driver sends the generic status code instead of protocol
status code.
As a workaround, assign the seqNumber=4 for AUTH frame 4,
which ensures driver to send correct status code when WEP AUTH
fail.
