Subject: [PATCH v2] bnxt_en: use new module_firmware_crashed()

This makes use of the new module_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.

v2: Move call module_firmware_crashed() to bnxt_fw_fatal_recover().
This will optimize to make the call at one central place.

Please append to the patchset:
