38dd7cc776 s390/css: Fix subchannel detection
We have to consider the m bit to find the real channel subsystem when
determining the last subchannel.

If we fail to take this into account, removal of a subchannel in
the middle of a big list of devices will stop device detection after
a reboot.

91b0a8f334 s390: Fix handling of iscs.
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.

8d034a6fad s390: css error codes.
Changed error codes in the channel subsystem / virtio-ccw code
(-EOPNOTSUPP -> -ENOSYS, -ERESTART -> -EINPROGRESS).

This should hopefully fix building on mingw32.
