usb: fsl_qe_udc: check qe_alloc_request() failure in ch9getstatus()
qe_alloc_request() may return NULL on allocation failure. ch9getstatus()
passes the return value directly to container_of() and then immediately
dereferences the resulting qe_req pointer. Check the allocation result
before using it and stall the control request on failure.
