s390/cio: fix irq statistics
When we fetch an interrupt on the CCW console using tsch (via
ccw_device_wait_idle formerly known as wait_cons_dev) we increment
the irq count for the affected interruption class but it is not
accounted as an IO interrupt.
This is broken since commit b603d258a43b4e7339660bdd3b5c25eacd603e54
"s390: remove superfluous tpi from wait_cons_dev"
Fix it so that the sum of the individual interrupts per class matches
the number of IO interrupts again.
