devtmpfsd: fix task state handling
- Set the state to TASK_INTERRUPTIBLE using __set_current_state() instead of set_current_state() as the spin_unlock is an implicit memory barrier. - After return from schedule(), there is no need to set the current state to TASK_RUNNING - a call to schedule() always returns in TASK_RUNNING state.
