scsi: qla2xxx: Handle PCIe error for driver
Driver will perform following - Set PFLG_DRIVER_REMOVING flag and do not disable PCIe error reporting during adapter shutdown. - If PCIe device count is already zero, return correct error type from PCI error interface. - When device is offline, return correct error type from PCIe error path. - If there is board disable thread active during shutdown and PCIe device count is zero then cancel scheduling board disable thread during shutdown and return.
