Subject: [PATCH] pktgen: Remove fill_imix_distribution() CONFIG_XFRM dependency

From: Nick Richardson <richardsonnick@...gle.com>

Currently, the declaration of fill_imix_distribution() is dependent
on CONFIG_XFRM. This is incorrect.

Move fill_imix_distribution() declaration out of #ifndef CONFIG_XFRM
block.
