RPC Binder: -ECONNRESET => DEAD_OBJECT

This is for consistency with kernel binder. Sometimes, socket
failures result in -ECONNRESET when the connection is not
available. Right now, this may be thrown as a different error,
and we will only recover after the next transaction returns
the DEAD_OBJECT error. Coalesce this error so that we have
consistent behavior between kernel and RPC binder.
