Subject: [PATCH 4.20 093/183] SUNRPC: Ensure rq_bytes_sent is reset before request transmission

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit e66721f0436396f779291a29616858b76bfd9415 ]

When we resend a request, ensure that the 'rq_bytes_sent' is reset
to zero.
