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.
