[PATCH v2 5/7] imsm: allow to assemble with PPL even if dirty degraded

[Artur Paszkiewicz <artur.paszkiewicz@intel.com>]

From: Pawel Baldysiak <pawel.baldysiak@intel.com>

This is necessary to allow PPL recovery in the kernel driver. If the
recovery succeeds, the array is no longer in dirty state and can be
started normally as degraded.
