LU-10808 lod: align wrong DoM stripe values with defaults

LU-10808 lod: align wrong DoM stripe values with defaults

- Align DoM component size to the server limit size instead of
  returning a error. Error is returned still if DoM file creation
  is disabled on the server (DOM limit is set to 0)
- Correct wrong values for dom_stripesize parameter by using minimal
  stripe size if provided value is lower and by aligning it to be a
  multiple of that minimal size.
