    arm: vgic: Use find_first_bit instead of find_next_bit when possible
    find_next_bit(foo, sz, 0) is equivalent to find_first_bit(foo, sz). The
    latter is easier to understand. Some architecture may also have a
    optimized version of find_first_bit(...). So replace the occurrence of
    find_next_bit in vgic_vcpu_pending_irq()."
