[PATCH 2/2] imsm: don't update migration record when reshape is interrupted

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

Abort imsm_manage_reshape() without updating the migration record if any
error occurs when checking progress. If reshape is interrupted and the
migration record is then updated, the checkpoint will be wrong and will
cause reshape to fail when the array is restarted.
