Subject: [PATCH 12/13] ftgmac100: Remove useless tests in interrupt handler

From: Benjamin Herrenschmidt <[email-masked]>
Date: Sun, 2 Apr 2017 13:35:22 +1000

The interrupt is neither enabled nor registered when the interface
isn't running (regardless of whether we use nc-si or not) so the
test isn't useful.
