Actually I made a mistake in this. BLKSECTGET (the one in the block
layer) returns the number of "sectors", which is "defined" as 512-byte
block. So we shouldn't use BLKSSZGET here, but simply 512 (1 << 9).
See logical_to_sectors() in sd.h of the kernel.

We can and should get max transfer length and max segments for all host
devices / cdroms (on Linux).
Also use MIN_NON_ZERO instead when we clamp max transfer length against
max segments.
