Avoid warning when building with NDEBUG 

The assert macro is compiled out with NDEBUG which can lead to an unused
variable warning if the variable is only read in the assert. This is
seen just here:

dwarf_loader.c:957:17: error: unused variable 'tag' [-Werror,-Wunused-variable]
        const uint16_t tag = dwarf_tag(die);
