[PATCH stable 4.9 v2 29/29] ipv4: frags: precedence bug in ip_expire()

[Florian Fainelli]

From: Dan Carpenter <dan.carpen...@oracle.com>

(commit 70837ffe3085c9a91488b52ca13ac84424da1042 upstream)

We accidentally removed the parentheses here, but they are required
because '!' has higher precedence than '&'.

Fixes: fa0f527358bd ("ip: use rb trees for IP frag queue.")
