Subject: iwlwifi: Fix MODULE_FIRMWARE() for non-existing ucode version
Patch-mainline: Never, temporary workaround
References: boo#1191417

iwlwifi driver declares the requested firmware *-72.ucode for 22000
series, but that version isn't found in the upstream linux-firmware
tree.  As a result, the installation image (and initrd) misses the
requested firmware, which leads to the non-working WiFi.

As a temporary fix, correct the ucode version to the existing one,
*-71.
