[S390] qdio: fix kernel panic for zfcp 31-bit

The queue_start_poll function pointer field in struct qdio_initialize
had to change its type and become a vector of function pointers to
support asynchronous delivery of storage blocks so rename the field to
make the type change explicit and ensure no other user of qdio tries
to use the field the old way. During setting up the qdio queues, only
dereference vector elements if the vector is actually allocated.
