Kishon Vijay Abraham I b4c21f0bdd usb: gadget: composite: Fix NULL pointer dereference ...

commit f563d23090 ("usb: gadget: composite: add req_match method
to usb_function") accesses cdev->config even before set config
is invoked causing a NULL pointer dereferencing error while running
Lecroy Mass Storage Compliance test.

Fix it here by accessing cdev->config only if it is non NULL.

Fixes: commit f563d23090 ("usb: gadget: composite: add req_match
method to usb_function").
