Revert "Revert "ANDROID: usb: dwc3: gadget: don't cancel the started requests""

This reverts commit 17f230fd93.

Reason for revert: adb connection is unstable on Mac C-C setup and breaking
the workflow for a lot of people.

We can revert this later if we find and fix any userspace issues that might
be causing this.
