[PATCH rhel6-branch] Increment MD container child counter even if its volumes are ignored (#1120640)

[Artur Paszkiewicz]

Volumes which are not selected in Specialized Storage Devices are
ignored in addUdevDevice. This causes that their parent container
won't have its child counter incremented, which can later cause an
incorrect unusedRaidMembersWarning.
