Haoxiang Li cc8f92e41e w1: fix redundant counter decrement in w1_attach_slave_device() 
In w1_attach_slave_device(), if __w1_attach_slave_device() fails,
put_device() -> w1_slave_release() is called to do the cleanup job.
In w1_slave_release(), sl->family->refcnt and sl->master->slave_count
have already been decremented. There is no need to decrement twice
in w1_attach_slave_device().

Fixes: 2c927c0c73 ("w1: Fix slave count on 1-Wire bus (resend)")
