scsi: Rename linux-specific SG_ERR codes to generic SCSI_HOST error codes
We really should make a distinction between legitimate sense codes
(ie if one is running against an emulated block device or for
pass-through sense codes), and the intermediate errors generated
during processing of the command, which really are not sense codes
but refer to some specific internal status. And this internal
state is not necessarily linux-specific, but rather can refer to
the qemu implementation itself.
So rename the linux-only SG_ERR codes to SCSI_HOST codes and make
them available generally.
