usb: dwc3: gadget: Fix logical condition 

commit 8c7d4b7b3d 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.

Fixes: f38e35dd84 ("usb: dwc3: gadget: split dwc3_gadget_ep_cleanup_completed_requests()")
