Subject: [PATCH 4.4 265/312] et131x: Fix logical vs bitwise check in et131x_tx_timeout()

From: Florian Fainelli <f.fainelli@...il.com>

commit de702da7a823ab0c4a1e53ed79a2695f0d453855 upstream.

We should be using a logical check here instead of a bitwise operation
to check if the device is closed already in et131x_tx_timeout().
