[PATCH 1/3] Revert "drm/amdgpu: fix a mistake when removing mem_info_preempt_used sysfs"

[Jesse.zhang@amd.com]

From: "Jesse.zhang at amd.com" <Jesse.zhang at amd.com>

This reverts commit 10aec8943bcc5123288ded8c97e78312bcf17fb1.
the dev->unplugged flag will also be set to true ,
Only uninstall the driver by amdgpu_exit, not actually unplug the device.
that will cause a new issue.
