[PATCH 2/4] Documentation: e1000: Use correct heading adornment

[Tobin C. Harding]

Recently documentation file was converted to rst.  The document title
has the incorrect heading adornment.  From kernel docs:

	* Please stick to this order of heading adornments:

	  1. ``=`` with overline for document title::

	       ==============
	       Document title
	       ==============

Add  overline heading adornment to document title.

Fixes commit (228046e76189 Documentation: e1000: Update kernel documentation)
