qcacld-3.0: Add support for connection failure cases with no roam_info

hdd_association_completion_handler function calls with
roam_info set to NULL are not handled. Due to this the conn_state
remains in eConnectionState_Connecting state. Hence add handling for
connection failure with no roam info.
