yukangzhi bcddaa59a9 drivers/pipe: fix POLLHUP handling in poll() ...

For POLICY_0, when a pipe only has a reader and no writer,
if the pipe is empty, set POLLHUP.

For POLICY_1, when a pipe only has a reader but no writer,
if the pipe is empty, POLLHUP will not be set.

This change corrects poll() behavior to match the two pipe policies.
No API changes.
