The QOM realizefn cannot depend on errp being non-NULL as in

There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.

Unfortunately, we have treated to I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as
- (queued-for-next) kvm made the same mistake, and
- Linux guest kernels don't check the isc value in the I/O interruption
  word for subchannel interrupts.

Make sure that we treat the I/O interruption word correctly.

do_io_interrupt() would stop scanning further iscs if it found
an I/O interrupt it could inject. This might cause the pending
interrupt indication for I/O interrupts to be reset although there
might be queued I/O interrupts for subsequent iscs.

Fix this by reordering the logic: Inject the I/O interrupt immediately
and continue searching all iscs for queued interrupts.
