usb: gadget: u_ether: Convert prints to device prints
[ Upstream commit 938fc645317632d79c048608689683b5437496ea ]
The USB ethernet gadget driver implements its own print macros which
call printk. Device drivers should use the device prints that print the
device name. Fortunately, the same macro names are defined in the header
file 'linux/usb/composite.h' and these use the device prints. Therefore,
remove the local definitions in the USB ethernet gadget driver and use
those in 'linux/usb/composite.h'. The only difference is that now the
device name is printed instead of the ethernet interface name.
Tested using ethernet gadget on Jetson AGX Orin.
