From: Eric Biggers <ebiggers@xxxxxxxxxx>
Commit 6917d0689993 ("block: merge invalidate_partitions into
rescan_partitions") caused a regression where systemd-udevd spins
forever using max CPU starting at boot time.
It's caused by a behavior change where a KOBJ_CHANGE uevent is now sent
in a case where previously it wasn't.
Restore the old behavior.
Fixes: 6917d0689993 ("block: merge invalidate_partitions into rescan_partitions")
