[dpdk-dev] [PATCH v2] rte: initialize logging before bus

[Stephen Hemminger <stephen@networkplumber.org>]

Any log messages during bus initialization maybe lost because
the bus registration constructor is called before the logging constructor.

Fixes: a97725791eec ("bus: introduce bus abstraction")
