dm_flush_nap_nosync() only removes a device if it has a multipath table.
On failed removes, there is no table, so this function does nothing.
Instead, if libmp_mapinfo() returns DMP_EMPTY, then there is an empty map,
and it is removed using dm_device_remove().
Also, since there are no longer any callers of dm_flush_map_nosync(),
remove it.
