     xfs: zero allocation_args on the kernel stack

     Zero the kernel stack space that makes up the xfs_alloc_arg structures.

Without the stack switching patches in the tree, this doesn't fix
any real problem.

Cheers,

Dave.

There are other users of the xfs_alloc_arg.userdata other than the
former version of the allocation worker.

--Mark.
