Paolo Bonzini 84f94a9a82 scsi-disk: correctly implement WRITE SAME 
Fetch the data to be written from the input buffer.  If it is all zeroes,
we can use the write_zeroes call (possibly with the new MAY_UNMAP flag).
Otherwise, do as many write cycles as needed, writing 512k at a time.

Strictly speaking, this is still incorrect because a zero cluster should
only be written if the MAY_UNMAP flag is set.  But this is a bug in qcow2
and the other formats, not in the SCSI code.
