addons: vrf: fix check for max vrf dev count

Browse Source 
Ticket: CM-10465
Reviewed By: julien, nikhil
Testing Done: Tested creating more than 64 vrf devices

example config:
{noformat}
%for v in range(1, 66):
auto vrf${v}
iface vrf${v}
        vrf-table auto
%endfor
{noformat}

also, since vrf module already does a link up on vrf dev, remove
link up of vrf dev from ifupdownmain scheduler callback
