nfs: add minor version to nfs_server_key for fscache
An NFS client that mounts multiple exports from the same NFS
server with higher NFSv4 versions disabled (i.e. 4.2) and without
forcing a specific NFS version results in fscache index cookie
collisions and the following messages:
[ 570.004348] FS-Cache: Duplicate cookie detected
Each nfs_client structure should have its own fscache index cookie,
so add the minorversion to nfs_server_key.
