This fixes a bug and cleans up tunnelid range size
calculation code by using consistent variable names
and checks in size calculation and fill functions.

tested for a few cases of vlan-vni range mappings:
(output from patched iproute2):
$bridge vlan showtunnel
port     vid        tunid
vxlan0   100-105    1000-1005
         200        2000
         210        2100
         211-213    2100-2102
         214        2104
         216-217    2108-2109
         219        2119

We have many gro cells users, so lets move the code to avoid
duplication.

This creates a CONFIG_GRO_CELLS option.
