libcurl: reset rewind flag in curl_easy_reset()

curl_easy_reset() did not reset the `rewind_read` flag. This caused any
handles that previously had a CURLE_SEND_FAIL_REWIND error to get stuck
with that error, failing any subsequent requests, even if they didn't
have any body at all.

Verified in test 3034

Fixes #18206
Closes #18207
