tracing: Use ? : shortcut in trace macros

Instead of having:

  #define __assign_str(dst, src)					\
	memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ?		\
		__data_offsets.dst##_ptr_ : "(null)",			\
		__get_dynamic_array_len(dst))

Use the ? : shortcut and compact it down to:

  #define __assign_str(dst, src)					\
	memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ? : "(null)",	\
	       __get_dynamic_array_len(dst))
