[PATCH] scsi: sr: Fix some cdroms automatically ejected when booting into the system

From: jinxiaobo
Date: Wed Apr 27 2022 - 07:27:11 EST

sr_get_events() has been called before udev starts when SCSI CDROM is
built-in and AHCI SATA is bulit-in,so sr events propagated to
user space are not handled.
if both is loadable, udev will handle sr events, some cdroms may eject.
We need call sr_get_events() once before device_add_disk()
to keep the same result, whether both are built-in or loadable.
