Subject: scsi: qla2xxx: Delay I/O Abort on PCI error

From: Quinn Tran <qutran@xxxxxxxxxxx>

commit 591c1fdf2016d118b8fbde427b796fac13f3f070 upstream.

Currently when PCI error is detected, I/O 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 I/O
through the pci_error_handlers api.  Set eeh_busy flag to pause all traffic
and wait for I/O to drain.
