Subject[PATCH 5.2 49/56] rocker: fix memory leaks of fib_work on two error return paths
Date
From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 011f175428d46461f94a65dacb9a416529d08dda ]

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")
