    Don't clear osd_memory_target unconditionally

    The charm can now set osd_memory_target, but it's not per device class
    or type by the nature of how the charm works. Resetting
    osd_memory_target always when osd_memory_target is not passed over the
    relation is a bit risky behavior since operators may have set
    osd_memory_target by hand with `ceph config` command out side of the
    charm. Let's be less disruptive on the charm upgrade.
