Fix polling transfer restart after InterruptStop

Fix the regression introduced in the "Fix InterruptStop if called
before InterruptRead" commit: it should be possible to start a new
polling transfer after the previous one has been stopped.

This problem prevented the polling transfer from working after an
SCardDisconnect call, and led to using the sleep-based polling every
400 ms.

Implementation-wise, the fix is to change the "terminate" flag to be
non-sticky, i.e., unset it after reading from it.
