dmaengine: pl330: fix warning in pl330_remove



When removing a device with less than 9 IRQs (AMBA_NR_IRQS), we'll get a
big WARN_ON from devres.c because pl330_remove calls devm_free_irqs for
unallocated irqs. Similarly to pl330_probe, check that IRQ number is
present before calling devm_free_irq.
