[PATCH] dmaengine: doc: Properly indent metadata title

[Vinod Koul]

The newly added metadata documentation title was not properly indented
resulting in doc buil break:

  Sphinx parallel build error:
  docutils.utils.SystemMessage: /linux/Documentation/driver-api/dmaengine/client.rst:155: (SEVERE/4) Unexpected section title.

  Optional: per descriptor metadata
  ---------------------------------

Fix this by doing the right indent
