Disable SetReadDeadline calls

[aaronjheng]

I want to connect to Redis over SSH with golang.org/x/crypto/ssh. Currently ssh channels does not support deadlines. See golang/go#65930.

So the following calls should be disabled.

• redigo/redis/conn.go

  Line 748 in 247f6c0

  if err := c.conn.SetReadDeadline(deadline); err != nil {

• redigo/redis/conn.go

  Line 748 in 247f6c0

  if err := c.conn.SetReadDeadline(deadline); err != nil {

Right now, there is no way we can do that.
