net: phylink: fix failure to register on x86 systems
The kernel test robot reports a boot failure with qemu in 5.5-rc, referencing commit 2203cbf2 ("net: sfp: move fwnode parsing into sfp-bus layer"). This is caused by phylink_create() being passed a NULL fwnode, causing fwnode_property_get_reference_args() to return -EINVAL. Don't attempt to attach to a SFP bus if we have no fwnode, which avoids this issue.
