[PATCH] expand-on-first-boot: Fix "label: gpt" detection

[Uladzimir Bely <ubely@ilbers.de>]

Commit 991d2e9 introduced the issue when the whole script early exits
(due to "set -x") in case grep doesn't find the pattern and produces
an error code.

In this case last partition remains non-expanded.

Fix this by masking error with "echo 0".
