Subject: [PATCH 3/4] tools/bootconfig: Fix to return 0 if succeeded to show the bootconfig

Fix bootconfig to return 0 if succeeded to show the bootconfig
in initrd. Without this fix, "bootconfig INITRD" command
returns !0 even if the command succeeded to show the bootconfig.

Fixes: 950313ebf79c ("tools: bootconfig: Add bootconfig command")
