Common i/o layer fixes:
- Remove documentation entry for non-existent cio_notoper_msg parameter.
- Add documentation for availability attritube.
- Replace function of the steal_lock attribute by "echo force" to the
online attribute.
- Trigger device sensing in the online function for unknown devices.
- Always try to get devices online even if they are marked reserved.
Someone could have released the device while it was offline.
- Add try_module_get/module_put pairs to the online function of ccw devices
and ccwgroup devices.
- Add owner field to ccwgroup driver structure. Set owner field in ctc, lcs
and qeth.
- Fix alignment problems in channel measurement block interface.
