net: remove the new_ifindex argument from dev_change_net_namespace

Browse Source 
Here is only one place where we want to specify new_ifindex. In all
other cases, callers pass 0 as new_ifindex. It looks reasonable to add a
low-level function with new_ifindex and to convert
dev_change_net_namespace to a static inline wrapper.

Fixes: eeb85a14ee ("net: Allow to specify ifindex when device is moved to another namespace")
