net/mlx5e: IPoIB, Fix child PKEY interface stats on rx path

[ Upstream commit b5e23931c45a2f99f60a2f2b98a9e4d5a62a5b13 ]

The current code always does the accounting using the
stats from the parent interface (linked in the rq). This
doesn't work when there are child interfaces configured.

Fix this behavior by always using the stats from the child
interface priv. This will also work for parent only
interfaces: the child (netdev) and parent netdev (rq->netdev)
will point to the same thing.
