scsi: mpi3mr: Graceful handling of surprise removal of PCIe HBA
Implement graceful handling of surprise or orderly removal of PCIe HBA:
- Detect a hot removal of the controller at certain critical places in the
driver. Early detection will help to reduce the time taken for cleaning
up the hot-removed controller at the driver level.
- Poll the status of the port enable issued after reset once every 5
seconds to avoid a long delay in detecting unavailable controller.
