Merge branch 'ionic-FLR-support'

Shannon Nelson says:

====================
ionic: add FLR support

Add support for handing and recovering from a PCI FLR event.
This patchset first moves some code around to make it usable
from multiple paths, then adds the PCI error handler callbacks
for reset_prepare and reset_done.

Example test:
    echo 1 > /sys/bus/pci/devices/0000:2a:00.0/reset

v4:
 - don't remove ionic_dev_teardown() in ionic_probe() in patch 2/4
 - remove clear_bit() change from patch 3/4
