[PATCH] net/sunrpc/clnt.c compile fix

net/sunrpc/clnt.c does not compile if RPC_DEBUG is not enabled, due to
the fact that tk_pid is protected by RPC_DEBUG (which in turn depends on
CONFIG_SYSCTL).

The printk's that use it don't actually need to print it out at all,
the rpc_task tag isn't really interesting here.

Acked by Trond Myklebust.
