usb: dwc3: gadget: use explicit 0 for success in __dwc3_gadget_kick_transfer()

Browse Source 
Smatch warns that __dwc3_gadget_kick_transfer() might be missing an
error code when returning 'ret' at line 1691.

While 'ret' is guaranteed to be 0 at this point, returning an explicit 0
improves readability by removing a level of indirection and clarifies
the intent that this is a successful "no-op" path. This change also
silences the Smatch warning.
