Due to the conversion of the .debugfs_init() hook to return void
(drm: convert the .debugfs_init() hook to return void), there
is no need for the return value of qxl_debugfs_init(). Therefore,
refactor the function to return void.
This change also includes the conversion of various functions that can
be converted to return void as a result of the changes to
qxl_debugfs_init().
