commit 0b60f9ead5d4816e7e3d6e28f4a0d22d4a1b2513 (s390: use
device_remove_file_self() instead of device_schedule_callback())
caused random memory corruption on my s390 box. Turns out that the
last element of the ccwgroup structure is of dynamic size, so we
must move the newly introduced work structure _before_ the zero
length array.
