    Fix number of allowed missed messages from pmon in hostwd

    The following commit attempted to fix failure logic in hostwd:
    4150f91ff0687268e094a58ab177a12d56e97114
    hostwd_failure_threshold has been reduced from 5 to 3 in it, but the
    logic around pmon_grace_loops hasn't been touched.
    hostwd_failure_threshold is still reduced by 2 every time we miss a
    message from pmon. So, we only allow 1 missed message before the reboot.
    Removing this double substraction and reverting to old beavior:
    allow 2 missed messages from PMON and reboot a system on a 3rd one.
