Resery 340d6aa97c unicornafl: fix malloc of size 0 (#2010) ...

* bugfix: free a chunk with a size of 0, it will cause 1 byte oob.

Malloc does not check the size. Generally, malloc(0) should return 0 but there will return two pages. Free will use is_buffer_in_chunk to check whether the address is in the chunk. At that time, the chunk.data_addr == total_size . Free pass address and "1" to is_buffer_in_chunk. So cause 1 byte out-of-bound.

* typo
