SUNRPC: Rename "call_" functions that are no longer FSM states
The RPC client uses a finite state machine to move RPC tasks through each step of an RPC request. Each state is contained in a function in net/sunrpc/clnt.c, and named call_foo. Some of the functions named call_foo have changed over the past few years and are no longer states in the FSM. These include: call_encode, call_header, and call_verify. As a clean up, rename the functions that have changed. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
