s390/numa: allocate memory with correct alignment



Allocating memory with a requested minimum alignment of 1 is wrong
since pg_data_t contains a spinlock which requires an alignment of 4
bytes.

Therefore fix this and ask for an alignment of 8 bytes like it is
guarenteed for all kmalloc requests.
