Subject: [PATCH] sd-journal: Ignore data threshold if set to zero in
 sd_journal_enumerate_fields()

According to the documentation, Setting the data threshold to zero disables the
data threshold alltogether. Let's make sure we actually implement this behaviour
in sd_journal_enumerate_fields() by only applying the data threshold if it exceeds
zero.

(cherry picked from commit adbd80f51088058d55e703abe0ac11476cfe0ba4)
