From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when netdev fails to allocate the error return path
fails to free the allocated object 'lid'. Fix this by setting
err to the return error code and jumping to a new label that
performs the kfree of lid before returning.
Addresses-Coverity: ("Resource leak")
Fixes: 4b03b27349c0 ("ionic: get MTU from lif identity")
