[PATCH for-7.1 0/2] scsi-disk: fixes for block size crashes found by fuzzer

[Mark Cave-Ayland]

These two patches fix a couple of issues which were found by the fuzzer as a
consequence of allowing the guest to change the SCSI block size in commit
356c4c441e ("scsi-disk: allow MODE SELECT block descriptor to set the block 
size").

Mark Cave-Ayland (2):
  scsi-disk: fix overflow when block size is not a multiple of
    BDRV_SECTOR_SIZE
  scsi-disk: ensure block size is non-zero and changes limited to bits
    8-15
