dev_*() assumes 'go' is already initialized, so need use pr_*() instead
of before 'go' initialized. Related warning (with allmodconfig under
hexagon):
CC [M] drivers/staging/media/go7007/go7007-usb.o
drivers/staging/media/go7007/go7007-usb.c: In function 'go7007_usb_probe':
drivers/staging/media/go7007/go7007-usb.c:1060:2: warning: 'go' may be used uninitialized in this function [-Wuninitialized]
Also remove useless code after 'return' statement.
