acl-plugin: tuplemerge: avoid batch-resize of the applied entries vector - VPP-1352
If the number of rules within a given partition exceeds the limit,
the split_partition() might get called, in which we calculate
the relaxed mask, create a new partition with that mask and
attempt to reallocate some entries from the overcrowded partition.
The non-TM code was pre-expanding the vector with rules by
the number of rules in the new ACL being applied - which
caused the split_partition() to iterate over the rules
filled with zeroes. Most of the time it is benign, but
if a newly created relaxed partition is such that these
entries can be "relocated", then the code attempts to
do so, which does not end well.
