73e87e02ec CAN: use hrtimers in can-bcm protocol
Make use of hrtimers to support high resolution capabilities, when
provided by the system clocksource.

The conversion to hrtimers additionally discovered and solved an
unlikely race condition that has been reproduced under (unrealistic)
massive receive load, which can only be produced on vcan software devices.

[ Fix printf format warnings on 64-bit -DaveM ]

c346dca108 [NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.
Introduce per-net_device inlines: dev_net(), dev_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.
