inet: ipmr: fix data-races
Following fields of 'struct mr_mfc' can be updated
concurrently (no lock protection) from ip_mr_forward()
and ip6_mr_forward()
- bytes
- pkt
- wrong_if
- lastuse
They also can be read from other functions.
Convert bytes, pkt and wrong_if to atomic_long_t,
and use READ_ONCE()/WRITE_ONCE() for lastuse.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
