test/cuse: revert NVMe namespaces to default state 



If for any reason the cuse tests do not revert state
of NVMe namespaces to the original state, the test
machines would be stuck in until manual intervention.

Assumed default state is single namespace,
encompassing available space formatted as 4k block size.

This patch adds nvme_namespace_revert(), which
searches for NVMe devices that support Namespace Managment
and have some space unallocated.
When such device is found, all existing namespaces are removed
and single one created.

Fix #1435
