Subject: e100: Fix "disabling already-disabled device" warning
From: Michele Baldessari <[email protected]>
commit 2b6e0ca175fe4a20f21ba82b1e7ccc71029c4dd4 upstream.
In https://bugzilla.redhat.com/show_bug.cgi?id=994438 and
https://bugzilla.redhat.com/show_bug.cgi?id=970480 we
received different reports of e100 throwing the following
warning:

This patch removes pci_disable_device() from __e100_shutdown().
pci_clear_master() is enough.
