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.
I skipped 9p, ceph, and sunrpc since those don't go via my tree.
I applied the rest because it's mostly small and won't cause too
many conflicts in the future.
Thanks.
