usb: raw-gadget: report suspend, resume, reset, and disconnect events

Update USB_RAW_IOCTL_EVENT_FETCH to also report suspend, resume, reset,
and disconnect events.

This allows the code that emulates a USB device via Raw Gadget to handle
these events. For example, the device can restart enumeration when it
gets reset.

Also do not print a WARNING when the event queue overflows. With these new
events being queued, the queue might overflow if the device emulation code
stops fetching events.

Also print debug messages when a non-control event is received.
