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.
