usb: gadget: composite: Protect cdev in composite_suspend()
With USB cable disconnect case, there is race happening when
composite_suspend() is being pre-empted just after getting
reference to cdev structure (suspend flow) and cdev->config
set to NULL as part of reset_config() (disconnect flow). This
results into composite_suspend() using bad value with cdev->config
which is resulting in some cases multiple time calling f->suspend().
Fix this issue by protecting cdev in composite_suspend() API.
