parisc: do not count IPI calls twice

Commit Message

Helge Deller Oct. 26, 2013, 10:26 p.m. UTC

The number of IPI calls is already visible as per-cpu IPI irq counters
in/proc/cpuinfo, so let's drop this additional counting.
This partly reverts:
cd85d55 parisc: more irq statistics in /proc/interrupts
