[PATCH] all: refactor coding style

[Tiwei Bie <tiwei.bie@intel.com>]

Remove the unwanted spaces before `;' across DPDK source code
by below one-liner with some minor manual refinements.

find . -name '*.[ch]' | xargs sed -i 's/\([^;(]\) \+;/\1;/g'

The fixes for cmdline library are skipped, because it has a
different coding style. It deserves a separate cleanup if
necessary. The fixes for drivers' base code are also skipped
to keep the base code intact.
