umc-bus.c: fix usage of device_trylock

Hi all.

I've not received any feedback about this patch, so I'm resending just to check if someone is going to take care of it.

The patch fixes the usage of device_trylock inside the driver umc-bus.c:
device_trylock has the same semantics of mutex_trylock, so it returns 1 if the lock has been acquired successfully.

Best regards,

Claudio

It was sent in the middle of the merge window, when we are scrambling to get other stuff done. It's still in my queue and will be handled after 3.7-rc1 is out, and I've caught up on my travel.

thanks,
