USB: gadget: smd: Retry usb_req submission on resume 



Controller driver might fail any usb_req submission when
BUS is in suspend state. If all usb_reqs are pending at
the driver level then on resume they never get queued
again and RX stall will be seen. Take care of this by
attempting to submit any idle rx usb_req on resume.
