scsi: sd: Add error handling support for add_disk()

mainline inclusion
from mainline-v5.16-rc1
commit 2a7a891f
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I81XCK

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2a7a891f4c406822801ecd676b076c64de072c9e

----------------------------------------

We never checked for errors on add_disk() as this function returned
void. Now that this is fixed, use the shiny new error handling.

As with the error handling for device_add() we follow the same logic and
just put the device so that cleanup is done via the scsi_disk_release().
