From: Tejas Joglekar <Tejas.Joglekar@xxxxxxxxxxxx>
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.
Fixes: f38e35dd84e2 ("usb: dwc3: gadget: split dwc3_gadget_ep_cleanup_completed_requests()")
