Subject: [next-queue PATCH v2 2/2] e1000e: Drop unnecessary __E1000_DOWN bit
 twiddling

From: Alexander Duyck <alexander.h.duyck@...ux.intel.com>

Since we no longer check for __E1000_DOWN in e1000e_close we can drop the
spot where we were restoring the bit. This saves us a bit of unnecessary
complexity.
