[PATCH] Documentation/vm/page_owner.rst: Fix syntax error and Describe details using table

[Shenghong Han]

Some syntax errors exist in "page_owner.rst". Thanks to Akira Yokosawa and
Haowen Bai for tips to help improve the documentation.

We try to fix them. Hope that the Documentation is showed as we expect.

Thanks Jonathan's suggestion.

This fix is a simpler than before.
And yes, It has built in my machine.

Best,
