s390/qdio: fill SL with absolute addresses

[ Upstream commit e9091ffd6a0aaced111b5d6ead5eaab5cd7101bc ]

As the comment says, sl->sbal holds an absolute address. qeth currently
solves this through wild casting, while zfcp doesn't care.

Handle this properly in the code that actually builds the SL.
