Commit 79a05a4e inadvertently removed the code necessary
to support multipath maps without partitions, as introduced
in b73a34ea "libmultipath: add skip_kpartx option". Revert
this part of the commit, so that skip_kpartx works again.
Fixes: 79a05a4e libmultipath: move suspend logic to _dm_flush_map
