PGLog: split divergent priors as well

Signed-off-by: Samuel Just <sjust@redhat.com>
(cherry picked from commit bbe231a61fc06a1a668e6b831fb8224526721f93)

Conflicts:
    src/osd/PGLog.h

    The cherry-picked commit did not compile as-is, because the hobject_t
    class in firefly lacks a get_hash() method, which was added in 6de83d4.
    To get the patch to compile, I replaced i->second.get_hash() with
    i->second.hash.
