futex: Set task::futex_state to DEAD right after handling futex exit
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.
