MFC r300881, r302058 (by asomers):
Avoid issuing spa config updates for physical path when not necessary

ZFS's configuration needs to be updated whenever the physical path for a
device changes, but not when a new device is introduced. This is because new
devices necessarily cause config updates, but only if they are actually
accepted into the pool.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c
        Split vdev_geom_set_physpath out of vdev_geom_attrchanged.  When
        setting the vdev's physical path, only request a config update if
        the physical path has changed.  Don't request it when opening a
        device for the first time, because the config sync will happen
        anyway upstack.

sys/geom/geom_dev.c
        Split g_dev_set_physpath and g_dev_set_media out of
        g_dev_attrchanged
