    arch: cxd56xx: Fix handle_irqreq() in cxd56_cpupause.c
    
    Summary:
    - The handle_irqreq() is used for remote IRQ control.
    - The logic is called via IPI (Inter-Processor Interrupt)
    - And the handler should handle only one request
    - However, I noticed that the handler handles up to two requests
    - This commit fixes this issue
    
    Impact:
    - Affects SMP cases only
    
    Testing:
    - Tested with spresense:wifi_smp
