Description

When configuring more than one flow manager, a single row between the per-flow-manager ranges is left-out.

The current code doesn't cover all rows when more than one flow manager is
used. It leaves a single row between ftd->max and ftd->min of the next
manager orphaned. As an example:

hash_size=1000
flowmgr_number=3
range=333

instance  ftd->min  ftd->max
0         0         333
1         334       666
2         667       1000

Rows not covered: 333, 666
