Vincent Mailhol c67732d067 can: annotate mtu accesses with READ_ONCE() ... As hinted in commit 501a90c945 ("inet: protect against too small mtu values."), net_device->mtu is vulnerable to race conditions if it is written and read without holding the RTNL. At the moment, all the writes are done while the interface is down, either in the devices' probe() function or in can_changelink(). So there are no such issues yet. But upcoming changes will allow to modify the MTU while the CAN XL devices are up. In preparation to the introduction of CAN XL, annotate all the net_device->mtu accesses which are not yet guarded by the RTNL with a READ_ONCE(). Note that all the write accesses are already either guarded by the RTNL or are already annotated and thus need no changes.
