qcacld-3.0: fix the wep unicast data transfer fail issue

The WEP security also use the open mode(key_mgmt is NONE), but
it will return directly if it is unicast and missed to call
csr_roam_issue_set_context_req() and then make the WEP unicast
data transfer fail.
So change to call csr_roam_issue_set_context_req() in this case.
