Saravana Kannan 75c00130e3 driver core: fw_devlink: Avoid spurious error message 
[ Upstream commit 6309872413 ]

fw_devlink can sometimes try to create a device link with the consumer
and supplier as the same device. These attempts will fail (correctly),
but are harmless. So, avoid printing an error for these cases. Also, add
more detail to the error message.
