[dm-devel] waiteventloop loops once more than it needs to

[Benjamin Marzinski <bmarzins redhat com>]

In waitevntloop(), you get the current event_nr, and then wait for an
event. After the event, the event_nr will always be at least one greater.
This means that waiteventloop will always run mark_failed_path() once more
than needed. This patch, against multipath-tools-0.4.4-pre15, fixes that.
