Subject: [PATCH 3/8] net: ipv6: delete these duplicate static variables two_five_five and minus_one

From: Wen Yang <[email protected]>

Since these static variables (two_five_five and minus_one) are only used
for boundary checks and will not be changed, remove them and use the ones
in our shared const array.
