SCSI fixes on 20160906
This is really three fixes, but the SES one comes in a bundle of three (making the replacement API available properly, using it and removing the non-working one). The SES problem causes an oops on hpsa devices because they attach virtual disks to the host which aren't SAS attached (the replacement API ignores them). The other two fixes are fairly minor: the sense key one means we actually resolve a newly added sense key and the RDAC device blacklisting is needed to prevent us annoying the universal XPORT lun of various RDAC arrays.
