Thomas Gleixner c2fd4e1198 futex: Set task::futex_state to DEAD right after handling futex exit 
commit f24f22435d upstream.

Setting task::futex_state in do_exit() is rather arbitrarily placed for no
reason. Move it into the futex code.

Note, this is only done for the exit cleanup as the exec cleanup cannot set
the state to FUTEX_STATE_DEAD because the task struct is still in active
use.
