[dpdk-dev] [PATCH v1] app/regex: change default qp configuration flags

[<guyk@marvell.com>]

From: Guy Kaneti <guyk@marvell.com>

By default qp configuration flags was set with
RTE_REGEX_QUEUE_PAIR_CFG_OOS_F.
Changed flags default to 0. In order to set OOS flag use
new argument --cfg_oos to config queue pair out of order scan.
