cephfs-top: navigate to home screen while selecting sort field, if no filesystems.

Fixes: https://tracker.ceph.com/issues/58813
Signed-off-by: Neeraj Pratap Singh <neesingh@redhat.com>
(cherry picked from commit db48c819bb28bd900df031a39ad687e7dc8ce6a5)

Conflicts:
	src/tools/cephfs/top/cephfs-top:self.active_screen is being
	changed to self.current_screen as this name change is not backported
	to pacific, so continuing with the name which exists in pacific.
