[PATCH 4.19 033/140] usb: dwc3: gadget: Fix logical condition

[Greg Kroah-Hartman]

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()")
