libdw: Don't use ATOMIC_VAR_INIT

ATOMIC_VAR_INIT was introduced in C11, but not deemed necessary to
implement atomics. So deprecated in C17 and removed in C23. Normal
initialization syntax should be sufficient.

	* libdw/libdw_alloc.c (next_id): Initialize to zero without
        using ATOMIC_VAR_INIT.
