Bug#808007: [PATCH] s390-dasd: check if DASD is already online

[Hendrik Brueckner]

Control: tags -1 + patch

Attach a patch to check if the DASD is already online because
trying to set a DASD online twice results in an error causing
the s390-dasd module to fail.

Thanks and kind regards,
  Hendrik
