[Gptfdisk-general] [BUG] gdisk exits with status 1 when successful

[Eric B. <ebi...@gm...>]

Since version 0.8.9 (commit 84aaff6b9cf3b802c621781cf9acd006aa5a3e66),
gdisk has exited with status 1 when listing the partition table with the
'l' option (and likely in other cases too, looking at the code).  The
success exit code should be changed back to 0 so that scripts don't think
there is an error.
