acl-plugin: tuplemerge: refresh the pointer to hash-readied ACL entries per each collision in split_partition() (VPP-1458)
A pointer to hash-ready ACL rules is only set once, which might cause a crash if there are colliding entries
from more than one ACL applied.
Solution: reload the pointer based on the element being processed.
