asan: heap buffer overflow in mmo_scan
mmo_get_loc needs to handle arbitrary vma and size chunks. Fuzzers
found that it wasn't working so well when the end of chunks were
getting close to address wrap-around.
* mmo.c (mmo_get_loc): Make "size" unsigned. Avoid arithmetic
overflow when calculating whether range hits an existing chunk.
