During IPsec RoCE TX creation a struct for the flow group creation is
allocated, but never freed. Free that struct once it is no longer in use.

Fixes: 22551e77e550 ("net/mlx5: Configure IPsec steering for egress RoCEv2 traffic")

Changelog:
v1:
 * Changed target from net-next to net.
 * Replaced goto labels to mark what they do.
v0: https://lore.kernel.org/all/1b414ea3a92aa0d07b6261cf641445f27bc619d8.1676811549.git.leon@kernel.org

It's there:

https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=c749e3f82a15e10a798bb55f60368ee102c793cb

But keep in mind that master is gone (long live main).
