[PATCH net-next] net/mlx5e: Fix possible memory leak

[Wei Yongjun]

From: Wei Yongjun <weiyongj...@huawei.com>

'encap_header' is malloced and should be freed before leaving from
the error handling cases, otherwise it will cause memory leak.

Fixes: 232c001398ae ("net/mlx5e: Add support to neighbour update flow")
Signed-off-by: Wei Yongjun <weiyongj...@huawei.com>
