s390/cio: Split pfn_array_alloc_pin into pieces
The pfn_array_alloc_pin routine is doing too much. Today, it does the
alloc of the pfn_array struct and its member arrays, builds the iova
address lists out of a contiguous piece of guest memory, and asks vfio
to pin the resulting pages.
Let's effectively revert a significant portion of commit 5c1cfb1c3948
("vfio: ccw: refactor and improve pfn_array_alloc_pin()") such that we
break pfn_array_alloc_pin() into its component pieces, and have one
routine that allocates/populates the pfn_array structs, and another
that actually pins the memory. In the future, we will be able to
handle scenarios where pinning memory isn't actually appropriate.
