[Libguestfs] [PATCH] Fix swapon_label test

[Matthew Booth]

The swapon label test has a side-effect, in that it creates a new partition.
This causes the later failure of the list_partitions test.

This change causes the swapon_label test to scrub /dev/sdb after the test, and
then re-read the partition table.
