hw/intc/aspeed: Fix IRQ handler mask check

Updated the IRQ handler mask check to AND with select variable.
This ensures that the interrupt service routine is correctly triggered
for the interrupts within the same irq group.

For example, both `eth0` and the debug UART are handled in `GICINT132`.
Without this fix, the debug console may hang if the `eth0` ISR is not
handled.
