Mark Johnston e6aed06fdf pf: Fix table entry counter toggling
When updating a table, pf will keep existing table entry structures
corresponding to addresses that are in both of the old and new tables.
However, the update may also enable or disable per-entry counters which
are allocated separately.  Thus when toggling PFR_TFLAG_COUNTERS, the
entries may be missing counters or may have unused counters allocated.

Fix the problem by modifying pfr_ina_commit() to transfer counters
from or to entries in the shadow table.
