usb: gadget: composite: avoid warning on aborted delayed status
A SET_CONFIGURATION request that disables the current configuration, or a
disconnect, can abort a control transfer whose status stage was delayed by
a function driver. The asynchronous function work can nevertheless finish
later and call usb_composite_setup_continue() after reset_config() has
cleared delayed_status.
This is an expected consequence of aborting the old control transfer, and
does not require a kernel warning. Keep the diagnostic available under
dynamic debug and ignore the obsolete completion as before.
