[PATCH 19.11 2/3] ethdev: add missing C++ guards

[Brian Dooley <brian.dooley@intel.com>]

[ upstream commit dbf9fc1dac70b64dd1ed9a3ffd6997838fbf170e ]

Some public header files were missing 'extern "C"' C++ guards,
and couldn't be used by C++ applications. Add the missing guards.

Fixes: 7a3f27c ("ethdev: add access to specific device info")
Fixes: dcd5c81 ("ethdev: add PCI driver helpers")
Fixes: 7f0a669 ("ethdev: add allocation helper for virtual drivers")
