After a failed LUKS unlock attempt the password entry dialog shows the
error "Failed to open LUKS encryption".  Improve the user experience by
clearing that error message at the start of the next attempt to avoid
contradictory information with the main windows status of "Opening
encryption on $PARTITION" whilst performing the next unlock attempt.

Bug 795617 - Implement opening and closing of LUKS mappings
