Currently when PCI error is detected, IO is aborted
manually through the ABORT IOCB mechanism which is
not guaranteed to succeed.

Instead, wait for the OS or system to notify driver
to wind down IO through the pci_error_handlers api.
Set eeh_busy flag to pause all traffic and wait
for IO to drain.
