sfp: fix module initialisation with netdev already up
It was been observed that with a particular order of initialisation,
the netdev can be up, but the SFP module still has its TX_DISABLE
signal asserted. This occurs when the network device brought up before
the SFP kernel module has been inserted by userspace.
This occurs because sfp-bus layer does not hear about the change in
network device state, and so assumes that it is still down. Set
netdev->sfp when the upstream is registered to work around this problem.
