sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport
[ Upstream commit 4db9ad82a6c823094da27de4825af693a3475d51 ]
Since transport->sock has been set to NULL during reset transport,
XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the
xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request()
to dereference the transport->sock that has been set to NULL.
Fixes: 7196dbb02ea0 ("SUNRPC: Allow changing of the TCP timeout parameters on the fly")
