From: Roman Stratiienko <roman.stratiienko at globallogic.com>

At this point we are using part number sub-command to retrieve UUID
of the partition using it's name.

 part number mmc $mmcdev system_a system_a_index
 part uuid mmc $mmcdev:${system_a_index} system_a_uuid

Since 'part uuid' sub-command expects partition index in hex format and
'part number' returns decimal value, 'part uuid' command will provide
wrong UUID or fail.

Fixes: be683756f62034 ("cmd: part: Add 'number' sub-command")
