Upstream: reading from a client after connection upgrade.

Read event on a client connection might have been disabled during
previous processing, and we at least need to handle events.  Calling
ngx_http_upstream_process_upgraded() is a simpliest way to do it.

Notably this change is needed for select, poll and /dev/poll event
methods.
