Mikulas Patocka f16dba5dc6 dm snapshot: revert "fix a crash when an origin has no snapshots"
Commit 7ee06ddc40 ("dm snapshot: fix a
crash when an origin has no snapshots") introduced a regression in
snapshot merging - causing the lvm2 test lvcreate-cache-snapshot.sh
got stuck in an infinite loop.

Even though commit 7ee06ddc40 was marked
for stable@ the stable team was notified to _not_ backport it.

Fixes: 7ee06ddc40 ("dm snapshot: fix a crash when an origin has no snapshots")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
