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.

Trond: Also fix up protocol version number argument in nfs_find_client() to
use the correct u32 type.
