Oops I forgot max_transfer needs to be in bytes (and BLKSECTGET in sg
has always been implemented wrongly). Will send a new version.

sg_get_max_transfer_length() and sg_get_max_segments() have nothing
to do with the sg driver or SG_IO at all. They can be and should be
used on all host devices / cdroms (on Linux).
Also use MIN_NON_ZERO instead when we clamp max_sectors against
max_segments.
