op: remove clen header from resent requests
op: remove clen header from resent requests

With "conn: add Content-Length hdr before request signing", the clen
header is now added to the request hdrs linked list by the connection
layer prior to dispatch. This header needs to be removed on retry or
redirect, to ensure that it isn't duplicated for the resend.
