Impact: Remove KERN_ERR printk from drm_sysfs_suspend() as this is not
an error (presumably was added during development and debug and not
removed at a later point). Less technical may express concern when their
laptop comes out of suspend and prints kernel error messages at them,
even if it does actually work fine.
Testcase: Suspend and resume cycle on laptop. Error message should not
be present.
