Fix race in free() of fastbin chunk: BZ #15073
Perform sanity check only if we have_lock. Due to lockless nature of fastbins we need to be careful derefencing pointers to fastbin entries (chunksize(old) in this case) in multithreaded environments. The fix is to add have_lock to the if-condition checks. The rest of the patch only makes code more readable. * malloc/malloc.c (_int_free): Perform sanity check only if we have_lock.
