isdn: hisax: Replace the bogus access to irq stats
commit 40f08a724fcc21285cf3a75aec957aef908605c6 upstream.
Abusing irq stats in a driver for counting interrupts is a horrible
idea and not safe with shared interrupts. Replace it by a local
interrupt counter.
Noticed by the attempt to remove the irq stats export.
