drm: Match sysfs name in link removal to link creation

drm: Match sysfs name in link removal to link creation

This patch matches the sysfs name used in the unlinking with the
linking function. Otherwise, remove_compat_control_link() fails to remove
sysfs created by create_compat_control_link() in drm_dev_register().

Fixes: 6449b088dd51 ("drm: Add fake controlD* symlinks for backwards
compat")
