Geneve's Virtual Network Identifier (VNI) is 24 bit long, so the range
of values for it would be from 0 to 16777215 (2^24 -1). However, one
cannot create a geneve device with VNI set to 16777215. This patch fixes
this issue.

I always worry that someone, somewhere, might be using this in some
way and this will break things.
But I'll apply this for now.
Thanks David. As per the output of 'ip link help geneve', 16777215 is a valid
value. However, due to incorrect check in the kernel that value was not supported.
$ ip link help geneve |egrep -A1 VNI
Usage: ... geneve id VNI
remote ADDR
--
Where: VNI := 0-16777215
ADDR := IP_ADDRESS
So, this is an off-by-one bug and no one had tripped over it until now.
