[PATCH] aha152x_cs: Fix regression that keeps driver from using shared interrupts

At some point since 2.6.22, the aha152x_cs driver stopped working and started
erring on load with the following messages:

kernel: pcmcia: request for exclusive IRQ could not be fulfilled.
kernel: pcmcia: the driver needs updating to supported shared IRQ lines.

With the following change, the driver works with shared IRQs.
