[PATCH 09/18] bootstd: Work around missing partition 1

[Simon Glass]

If there is no partition numbered 1, we decide that there are no
partitions at all. That may not be correct, since at least one Debian
installed has just a single partition numbered 2.

Continue searching up to partition 3, just in case.
