pnfs/blocklayout: pass proper file mode to blkdev_get/put
We generally want to read and write to a block device that's used by
the pNFS block layout client (and even if it's read only the server
has no way of telling us). Add FMODE_WRITE to the mode argument
so that we don't incorrectly tell the block driver that we want a
read-only open.
