[dpdk-dev] [PATCH v2 4/5] kvargs: remove experimental function to compare string

[Olivier Matz <olivier.matz@6wind.com>]

The function was designed to be used as a handler for
rte_kvargs_process() to compare the value string in a kvlist. For
readability, its usages in DPDK have been replaced by
rte_kvargs_get_with_value() in previous commit.

Remove this function, as it is not used anymore.
