block/sheepdog: fix argument passed to qemu_strtoul()
The function qemu_strtoul() reads 'unsigned long' sized data,
which is larger than uint32_t on 64-bit machines.
Even though the snap_id field in the header is 32-bits, we must
accommodate the full size in qemu_strtoul().
This patch also adds more meaningful error handling to the
qemu_strtoul() call, and subsequent results.
