net: phy: phylink: Handle NULL fwnode_handle
Unlike the various of_* routines to fetch properties, fwnode_* routines can
have an early check against a NULL fwnode_handle reference which makes them
return -EINVAL (see fwnode_call_int_op), thus making it virtually impossible to
differentiate what type of error is going on.
Have an early check in phylink_register_sfp() so we can keep proceeding with
the initialization, there is not much we can do without a valid fwnode_handle
except return early and treat this similarly to -ENOENT.
Fixes: 8fa7b9b6af25 ("phylink: convert to fwnode")
