[S390] cio: Try harder to disable subchannel.
Acting upon the assumption that cio_disable_subchannel()
is only called when we really want to disable the subchannel
(a) remove the check for activity (it is already done in
ccw_device_offline(), which is the place where it matters)
(b) collect pending status via tsch() and ignore it (it
can't matter anymore since the subchannel will be disabled).
