Revert of Fix cronet crash on calling IsDataReductionProxyEnabled (patchset #4 id:60001 of https://codereview.chromium.org/
1308923003/ )
Reason for revert:
This does not help in fixing the cronet crash. Also, it is
calling data_reduction_proxy_service->GetWeakPtr() after
data_reduction_proxy_service has been Passed. After the
ownership is passed, data_reduction_proxy_service is
null.
