[RFC 1/4] net/af_packet: remove volatile from statistics

[Stephen Hemminger <stephen@networkplumber.org>]

Statistics are only updated from a single thread at a time and
the compiler should not have to worry about optimizing them.
The statistics returned are 64 bit so use uint64_t instead
of arch specific unsigned long.
