[dpdk-dev] [PATCH 1/3] cfgfile: remove unnecessary initialization

[Stephen Hemminger <stephen@networkplumber.org>]

No need to initialize variable if it is immediately overwritten.
It is better style not do unnecessary initialization with modern
tools since it lets compiler and other static checkers detect
uninitialized data.
