r8152: fix tx packets accounting

[ Upstream commit 4c27bf3c5b7434ccb9ab962301da661c26b467a4 ]

r8152 driver handles TSO packets (limited to ~16KB) quite well,
but pretends each TSO logical packet is a single packet on the wire.

There is also some error since headers are accounted once, but
error rate is small enough that we do not care.
