[PATCH v3 8/8] qed: use new taint_firmware_crashed()

From: Luis Chamberlain
Date: Tue May 26 2020 - 11:07:45 EST

This makes use of the new taint_firmware_crashed() to help
annotate when firmware for device drivers crash. When firmware
crashes devices can sometimes become unresponsive, and recovery
sometimes requires a driver unload / reload and in the worst cases
a reboot.

Using a taint flag allows us to annotate when this happens clearly.
