qcacld-3.0: Provide correct status code in case of no ack

Currently, LIM_ACK_NOT_RCD is not handled while filling
status code due to which STATUS_UNSPECIFIED_FAILURE is
updated as part of default handling instead of
STATUS_AUTH_NO_ACK_RECEIVED. Don't overwrite previous
status code in case no ack received from peer.

Fix is to Handle LIM_ACK_NOT_RCD case while filling status
code and consider previous status code when no ack received
from peer.
