mlxsw: spectrum_router: Update prefix count for IPv6
The number of possible prefix lengths for IPv6 is 129 and not 128.
Fixes following warning from UBSAN when /128 routes are offloaded:
UBSAN: Undefined behaviour in
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:2510:27 index 128 is out
of range for type 'long unsigned int [128]'
Fixes: 5e9c16cc83a7 ("mlxsw: spectrum_router: Implement private fib")
