Subject: [PATCH] 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.

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