acl: fix build with gcc 5.4.0

gcc 5.4 fails with:
../lib/librte_acl/acl_run_avx512x8.h: In function 'match_process_avx512x8':
../lib/librte_acl/acl_run_avx512x8.h:382:31: error:
pointer targets in passing argument 1 of '_mm256_mask_i32scatter_epi32'
differ in signedness [-Werror=pointer-sign]

Later gcc versions work fine, as for them parameter type was
changed to 'void *'.
Fixed by applying explicit cast for offending argument.
