Refresh kernel partition table between tests (#779)

The test suite for ceph-iscsi does a bunch of operations on filesystems in quick succession, so some tests are prone to fail if the kernel doesn't update the partition table. This PR does this manually between tests by calling the 'partprobe' command. Co-authored-by: Luciano Lo Giudice <[email protected]>
