[PATCH 4.19 22/34] scsi: sr: Return appropriate error code when disk is ejected

[Greg Kroah-Hartman]

From: ManYi Li <limanyi@xxxxxxxxxxxxx>

[ Upstream commit 7dd753ca59d6c8cc09aa1ed24f7657524803c7f3 ]

Handle a reported media event code of 3. This indicates that the media has
been removed from the drive and user intervention is required to proceed.
Return DISK_EVENT_EJECT_REQUEST in that case.
