Your compiler wasn't very helpful. Or maybe we get better diagnostics with
a 64-bit compiler:



From: Randy Dunlap <rdunlap@xenotime.net>

Fix printk format warning(s):

drivers/usb/net/usbnet.c: In function 'usbnet_open':
drivers/usb/net/usbnet.c:654: warning: format '%d' expects type 'int', but argument 3 has type 'size_t'

The fact that rx_urb_size happens to be a size_t has propagated all the way
back to this printk. It's fragile to be using %z in this case - let's just
typecast the args instead.
