miscdevice: rust: use build_error! macro instead of function

The function called build_error is an implementation detail of the macro
of the same name. Thus, update miscdevice to use the macro rather than
the function. See [1] for more information on this.

These use the macro with the kernel:: prefix as it has not yet been
added to the prelude.
