s390: use device_remove_file_self() instead of device_schedule_callback()
driver-core now supports synchrnous self-deletion of attributes and the asynchrnous removal mechanism is scheduled for removal. Use it instead of device_schedule_callback(). * Conversions in arch/s390/pci/pci_sysfs.c and drivers/s390/block/dcssblk.c are straightforward. * drivers/s390/cio/ccwgroup.c is a bit more tricky because ccwgroup_notifier() was (ab)using device_schedule_callback() to purely obtain a process context to kick off ungroup operation which may block from a notifier callback. Rename ccwgroup_ungroup_callback() to ccwgroup_ungroup() and make it take ccwgroup_device * instead. The new function is now called directly from ccwgroup_ungroup_store(). ccwgroup_notifier() chain is updated to explicitly bounce through ccwgroup_device->ungroup_work. This also removes possible failure from memory pressure. Only compile-tested.
