net: phylink: avoid resolving link state too early
commit 87454b6edc1b0143fdb3d9853285477e95af74a4 upstream. During testing on Armada 388 platforms, it was found with a certain module configuration that it was possible to trigger a kernel oops during the module load process, caused by the phylink resolver being triggered for a currently disabled interface. This problem was introduced by changing the way the SFP registration works, which now can result in the sfp link down notification being called during phylink_create().
