pnfs/blocklayout: require 64-bit sector_t
commit 8a9d6e964d318533ba3d2901ce153ba317c99a89 upstream.
The blocklayout code does not compile cleanly for a 32-bit sector_t,
and also has no reliable checks for devices sizes, which makes it
unsafe to use with a kernel that doesn't support large block devices.
