net: 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.
