Merge branch 'net-whitespace-cleanups'

Stephen Hemminger says:

====================
net whitespace cleanups

Ran script that I use to check for trailing whitespace and
blank lines at end of files across all files in net/ directory.
These are errors that checkpatch reports and git flags.

These are the resulting fixes broken up mostly by subsystem.
