asan: mmo: NULL dereferenc in mmo_xore_32
mmo_get_loc can return NULL. It's commented even, and that the caller
then must handle a split field. mmo_xore_* don't handle split fields,
instead just segfault. Stop that happening, and refuse to recognise
fuzzed mmo files that trigger this problem.
* mmo.c (mmo_get_loc): Don't declare inline.
(mmo_xore_64, mmo_xore_32, mmo_xore_16): Remove forward decls.
Return pointer, don't dereference NULL.
(mmo_scan): Return error on mmo_get_loc returning NULL.
