43b2aef373 neighbor: tracing: Have neigh_create event use __string()
The dev field of the neigh_create event uses __dynamic_array() with a
fixed size, which defeats the purpose of __dynamic_array(). Looking at the
logic, as it already uses __assign_str(), just use the same logic in
__string to create the size needed. It appears that because "dev" can be
NULL, it needs the check. But __string() can have the same checks as
__assign_str() so use them there too.

9c03b282ba trace: events: add a few neigh tracepoints
The goal here is to trace neigh state changes covering all possible
neigh update paths. Plus have a specific trace point in neigh_update
to cover flags sent to neigh_update.
