usb: dwc3: gadget: Fix logical condition

commit 8c7d4b7b3d43c54c0b8c1e4adb917a151c754196 upstream.

This patch corrects the condition to kick the transfer without
giving back the requests when either request has remaining data
or when there are pending SGs. The && check was introduced during
spliting up the dwc3_gadget_ep_cleanup_completed_requests() function.
