[PATCH] xfstests: aio-stress is calling pthread_join incorrectly

[Dave Kleikamp <dave.kleikamp@oracle.com>]

The retval parameter to pthread_join() is a pointer to a pointer.
aio-stress is passing in a pointer to an int. This can result in a bus
error on sparc64 when the pointer is not aligned on a 64-bit boundary.
Since the return value is not used, it is simplest to pass a NULL
pointer instead.

This has been fixed in the LTP source:
