Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element.
Clean up the following coccicheck warning:
./tools/usb/usbip/src/usbipd.c:536:19-20: WARNING: Use ARRAY_SIZE.
Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Jiapeng Chong <jiapeng.chong@linux.alibaba.com> --- Changes in v2: -Add ARRAY_SIZE definition to usbip_common.h file.
