The opcode of the link status notification message reported by the
firmware is zero, it will be filtered out because driver treats it as
already processed message. As a result, the PF can't update the link
status in a timely manner.
Because only VF can set opcode to zero when processing mailbox message,
we add a judgment to make sure the PF messages will not be filtered out.
