scsi: smartpqi: Improve handling of multipath failover

Improve multipath failovers by mapping firmware errors into I/O errors.

In some rare instances, firmware does not return the proper error code for
I/O errors caused by a multipath path failure.

Map I/O errors returned by firmware into errors that help the multipath
layer to detect the failure of a path.
