Gabriel Krisman Bertazi 11b3c20bdd drm: Change the return type of the unload hook to void 
The integer returned by the unload hook is ignored by the drm core, so
let's make it void.

This patch was created using the following Coccinelle semantic script
(except for the declaration and comment in drm_drv.h):

Compile-tested only.
