There is no guarantee this will work because we are assuming
that all bytes are valid loclist data, that there are no
odd padding or garbage bytes. In normal use one gets
into here via an offset from .debug_info, so it could be
that bytes not referenced from .debug_info are garbage
or even zero padding. So this can fail (error off) as such bytes
can lead dwarf_get_loclist_entry() astray.
It is also broken because we do not know what CU is involved
so if address_size varies by CU we cannot know that here.
