    x86/IO-APIC: replace redundant irq_trigger() call
    
    Just having called the function and stored the result, there's no point in
    calling it again right away with the same argument; the stored result can
    be used instead. And the stored result also doesn't need overwriting again
    with the same value.
    
    No functional change intended.
