Subject: [PATCH] octeontx2-vf: Add missing free for alloc_percpu
References: bsc#1012628
Patch-mainline: 6.2.9
Git-commit: f038f3917baf04835ba2b7bcf2a04ac93fbf8a9c

[ Upstream commit f038f3917baf04835ba2b7bcf2a04ac93fbf8a9c ]

Add the free_percpu for the allocated "vf->hw.lmt_info" in order to avoid
memory leak, same as the "pf->hw.lmt_info" in
`drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.c`.
