[PATCH] winhttp: Always send a callback from async query_data_available

[Ross Lagerwall]

This fixes a regression where an async query to check for data available does
not send a callback when async is true and the end of read data occurs. This
was introduced by commit bb3097f01e53 (winhttp: Add a read-ahead buffer to
allow WinHttpQueryDataAvailable to return the right values in chunked mode.).
