watchdog: don't print error when allocating urb fails

This per-subsystem series is part of a tree wide cleanup. usb_alloc_urb() uses kmalloc which already prints enough information on failure. So, let's simply remove those "allocation failed" messages from drivers like we did already for other -ENOMEM cases. gkh acked this approach when we talked about it at LCJ in Tokyo a few weeks ago.

kmalloc will print enough information in case of failure.
