  • Brief description of the changes in this pull request:
    When loading multipath devices in rescue mode, ReaR rescue print to the user the name / UUID / size of the discovered multipath device.
    if multipath is used with "friendly_name" option, the output of the command multipath -l is

<friendly_mpath_name> (<mpath UUID>) <dm-name> <Vendor, type>
rootvg (3600507680c82004cf800000000000306) dm-2 IBM     ,2145

while it is a bit different when "friendly_name" is disabled

<mpath UUID> <dm-name> <Vendor, type>
36005076400810051380000000000007b dm-2 IBM,2145

=> "dm-" can be the 3rd or 2nd field.....
This means we have to adjust the awk to print the line where "dm-" appears and not when "dm-" is the 3rd field.
