Subject: [PATCH AUTOSEL 3.18 91/98] iwlwifi: pcie: correctly define 7265-D cfg

From: Arik Nemtsov <arikx.nemtsov@...el.com>

[ Upstream commit 2b0e2b0f7bfe9a9098bda6109176adcf78f9b7ac ]

The trans cfg was not replaced for 7265-D cards. This led to a check of
the min-NVM version against a 7265-C card, causing very-old 7265-D cards
to operate incorrectly with the driver.

Fixes: 3fd0d3c170ad ("iwlwifi: pcie: support 7265-D devices")
