Description of problem:
-----------------------
When NBDE setup is completed, the target device is created under /dev/mapper/luks_sdx. When attempting for RHHI-V deployment from web console(cockpit), and attaching the LVM cache, logic uses device name as '/dev/luks_sdc' instead of '/dev/mapper/luks_sdc'

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
cockpit-ovirt-dashboard-0.14.8


How reproducible:
-----------------
Always


Steps to Reproduce:
-------------------
1. Start the HC deployment from cockpit
2. On the bricks tab provide the device name as '/dev/mapper/luks_sdc'
3. Enable LVM cache and provide SSD as '/dev/sdg'

Actual results:
---------------
Generated inventory file contains reference to '/dev/luks_sdc'

Expected results:
------------------
Generated inventory file should contain '/dev/mapper/luks_sdc'

The generated inventory contains:

<snip>
      gluster_infra_cache_vars:
        - vgname: gluster_vg_luks_sdc
          cachedisk: '/dev/luks_sdc,/dev/sdg'
          cachelvname: cachelv_gluster_thinpool_gluster_vg_luks_sdc
          cachethinpoolname: gluster_thinpool_gluster_vg_luks_sdc
          cachelvsize: 220G
          cachemode: writethrough
</snip>

Expected is that the device should be */dev/mapper/luks_sdc*

        - vgname: gluster_vg_luks_sdc

This error is also true for multipath configuration enabled, where the device name is '/dev/mapper/WWID'

for example: /dev/mapper/3600304801a48610125f9a6571e612c29
