[patch 3/9] ipv6: use timer pending

[Greg KH]

2.6.25-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Stephen Hemminger <shemminger@xxxxxxxxxx>

[ Upstream commit 847499ce71bdcc8fc542062df6ebed3e596608dd ]

This fixes the bridge reference count problem and cleanups ipv6 FIB
timer management.  Don't use expires field, because it is not a proper
way to test, instead use timer_pending().
