Summary: wirefilter: unsigned long long overflow on delay calculation

Initial Comment:
As wirefilter keeps time in nanoseconds, a uint64 overflow is likely to occur.
Francesco A. aka lord_...@sf, who was investigating on wirefilter lockup for 
his thesis work, discovered this bug and already has a fix.

He is currently preparing a patch for commit. Please add him to the project as 
developer

Hi,

I'm working on my graduation thesis using kvm e vde2 to create a virtual
testbed.
During my tests frequently wirefilter stopped working, it didn't dequeue
packets because time variables apparently returned back in the past for the
overflow.
I'm including my proposed patch (that is working properly on testbed). If
it looks good, I would commit it in the next days.

Francesco
