ionic: fill out pci error handlers
Set up the pci_error_handlers error_detected and resume to be useful in
handling AER events. If the error detected is pci_channel_io_frozen we
set up to do an FLR at the end of the AER handling - this tends to clear
things up well enough that traffic can continue. Else, let the AER/PCI
machinery do what is needed for the less serious errors seen.
