Subject: [PATCH] rocker: fix memory leaks of fib_work on two error return paths

From: Colin Ian King <>

Currently there are two error return paths that leak memory allocated
to fib_work. Fix this by kfree'ing fib_work before returning.

Addresses-Coverity: ("Resource leak")
Fixes: 19a9d136f198 ("ipv4: Flag fib_info with a fib_nh using IPv6 gateway")
Fixes: dbcc4fa718ee ("rocker: Fail attempts to use routes with nexthop objects")
