NFS: Change nfs_find_client() to take "struct sockaddr *"

Adjust arguments and callers of nfs_find_client() to pass a "struct sockaddr *" instead of "struct sockaddr_in *" to support non-IPv4 addresses. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Aurelien Charbon <aurelien.charbon@ext.bull.net> Trond: Also fix up protocol version number argument in nfs_find_client() to use the correct u32 type.
