SCSI fixes on 20170401

Browse Source 
Thirteen small fixes: The hopefully final effort to get the lpfc nvme
 kconfig problems sorted, there's one important sg fix (user can induce
 read after end of buffer) and one minor enhancement (adding an extra
 PCI ID to qedi). The rest are a set of minor fixes, which mostly occur
 as user visible in error legs or on specific devices.
