Jeff Dike 438ee6798c uml: DEBUG_SHIRQ fixes ...

A couple more DEBUG_SHIRQ fixes.

The previous mconsole blocking fix exposed the lack of O_NONBLOCK on the
mconsole socket.

Also, winch_interrupt started crashing because it is called at irq free time
and it tries to dereference tty->driver_data, which has already been set to
NULL.

I added some error cleanup in mconsole_init while I was there.
