mei: me: fix clang -Wformat warning

When building with Clang we encounter the following warning:
| drivers/misc/mei/hw-me.c:564:44: error: format specifies type 'unsigned
| short' but the argument has type 'int' [-Werror,-Wformat]
| dev_dbg(dev->dev, "empty slots = %hu.\n", empty_slots);

The format specifier used is `%hu` which specifies an unsigned short,
however, empty_slots is an int -- hence the warning.
