Call __asan_free_hook() before marking the chunk quarantinned
Summary:
With this change, the user may safely call __asan_get_ownership()
from malloc/free hooks and assume it would return "true". If there is a
realloc/free race, free hook might be called twice, but I think it's acceptable,
as it's a data race and would later be reported anyway.
This change also fixes a bug when failing realloc incorrectly marked the
original memory as "quarantinned".
