qed: Fix possible race for the link state value.
There's a possible race where driver can read link status in mid-transition
and see that virtual-link is up yet speed is 0. Since in this
mid-transition we're guaranteed to see a mailbox from MFW soon, we can
afford to treat this as link down.
Fixes: cc875c2e ("qed: Add link support")
