[BUILD] CheckPatch: Quote variable to avoid error if empty
The variable is most likely empty if the according kernel headers directory was deleted. However, as it currently stands, cmake is complaining about too few arguments, which isn't really helpful to the user. Instead, quote the variable to make cmake finish, and have the actual compile process of the kernel module fail, which will yield a much more helpful error message.
