[PATCH] Cygwin: pty: Do not set input_available_event when applying line_edit()

The commit a0b38a81b9be sets input_available_event even if the
transferred input is still in the readahead buffer and is not ready
to read. The SetEvent() is called in accept_input() via line_edit(),
so setting this event here is not correct. This causes the issue
that read() returns 0 instead of blocking until accept_input() is
called. This patch removes this SetEvent() call.
