Subject: [RHEL7.5 PATCH 02/26] imsm: Allow create RAID volume with link to
 container

After 1db03765("Subdevs can't be all missing when create raid device")
raid volume can't be created with link to container. This feature should
not be blocked in Create function.  IMSM code forbids creation of
container with missing disk, so case like all dev's missing is already
handled.

Permit IMSM volume creation when devices are given as link to container.
