s390x/event-facility: fix location of receive mask
For read event mask, we assumed that the layout of the sccb was
|sccb header|event buffer header|receive mask|...|
The correct layout, however, is
|sccb header|receive mask|...|
as in-buffer and
|sccb header|event buffer header|...|
as out-buffer.
Fix this: This makes selective read work.
