Subject: [PATCH] ucc_geth: Do not bring the whole IF down when TX failure.

ucc_geth_close lacks a cancel_work_sync(&ugeth->timeout_work)
to stop any outstanding processing of TX fail. However, one
can not call cancel_work_sync without fixing the timeout function
otherwise it will deadlock. This patch brings ucc_geth in line with
gianfar:

Don't bring the interface down and up, just reinit controller HW
and PHY.
