Subject: [PATCH][next] ionic: fix memory leak of object 'lid'

From: Colin Ian King <>

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")
