[ Upstream commit c2255ff47768c94a0ebc3968f007928bb47ea43b ]
The failure to register devlink will leave the system with dangled
devlink resource, which is not cleaned if devlink_port_register() fails.
In order to remove access to ".registered" field of struct devlink_port,
require both devlink_register and devlink_port_register to success and
check it through device pointer.
Fixes: fbfb8031533c ("ionic: Add hardware init and device commands")
