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`.

I wonder if it wouldn't be more error prune when You create a function
to unroll cn10k_lmtst_init() like cn10k_lmtst_deinit(). These two if can
be there, maybe also sth else is missing.

Otherwise it is fine

I try my best and find nothing else missing.
