[PATCH v3 4/7] ipsec: fix missing explicit cast for C++ build

[Bruce Richardson <bruce.richardson@intel.com>]

C++ does not have automatic casting to/from void pointers, so need
explicit cast if header is to be included in C++ code

Fixes: f901d9c82688 ("ipsec: add helpers to group completed crypto-ops")
