input/async: reset the "open" flag after seeking successfully

Fixes a problem with the "curl" input plugin: IsEOF() always returns true because the "open" flag was cleared by CurlInputStream::RequestDone() when end-of-stream was reached. This flag stays false even when seeking to another position has succeeded. This patch resets the "open" flag to true after seeking successfully.
