vdev_id: Create symlinks even if no /dev/mapper/
vdev_id uses the /dev/mapper/ symlinks to resolve a UUID to a dm name
(like dm-1).  However on some multipath setups, there is no /dev/mapper/
entry for the UUID at the time vdev_id is called by udev.  However,
this isn't necessarily needed, as we may be able to resolve the dm
name from the $DEVNAME that udev passes us (like DEVNAME="/dev/dm-1").

This patch tries to resolve the dm name from $DEVNAME first, before
falling back to looking in /dev/mapper/.  This fixed an issue where the
by-vdev names weren't reliably showing up on one of our nodes.
