vvfat: fix qemu-img map and qemu-img convert
- bs->total_sectors is the number of sectors of the whole disk - s->sector_count is the number of sectors of the FAT partition This fixes the following assert in qemu-img map: qemu-img.c:2641: get_block_status: Assertion `nb_sectors' failed. This also fixes an infinite loop in qemu-img convert. Fixes: 4480e0f924a42e1db8b8cfcac4d0634dd1bb27a0 Fixes: https://bugs.launchpad.net/qemu/+bug/1599539 Cc: qemu-stable@nongnu.org Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
