Al Viro 10c890c0a3 um: switch close_chan() to struct line 
... and switch chan_interrupt() to directly calling close_one_chan(),
so we can lose delay_free_irq argument of close_chan() as well.

Al Viro 0fcd719934 um: race fix: initialize delayed_work *before* registering IRQ 
... since chan_interrupt() might schedule it if there's too much
incoming data.  Kill task argument of chan_interrupt(), while
we are at it - it's always &line->task.
