    watchdog/hpwdt: Remove redundant test.

    ProLiants of vintage to have an iLO 5, no longer send watchdog NMI
    as an IO CHECK.  They are presented to hpwdt_pretimeout as NMI_UNKNOWN.
    The preceding if statement rejects if !mynmi irrespective of value
    of pretimeout making this if statement redundant.
