    Fix bandwidth polling exception.

    When the bandwidth polling task tries to update bw usage for an
    instance that does not have an entry for the last two periods already
    in the bw_usage_cache table, it will throw an exception in the
    polling task. This was just a misses 'if' statement.

    Also:
    xenserver: fix swapped bw data in xs plugin.

    This fixes bug 1075255
