md/raid10: fix memleak of md thread
[ Upstream commit f0ddb83da3cbbf8a1f9087a642c448ff52ee9abd ]
In raid10_run(), if setup_conf() succeed and raid10_run() failed before
setting 'mddev->thread', then in the error path 'conf->thread' is not
freed.
Fix the problem by setting 'mddev->thread' right after setup_conf().
