[dpdk-dev] [PATCH] lib/librte_pipeline:fix the array index out of bound

[Rongqiang XIE]

In function rte_pipeline_compute_masks(), the value pos equal
p->entries[i]->action,type constraint p->entries[i]->action is
[0,4],but array action_mask1 size is 4,it possible attempt to
access element 4 of array action_mask1.And also in function
rte_pipeline_run(),it possible attempt to access element 4 of
array action_mask0.
