4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jail...@wanadoo.fr>
commit 990758c53eafe5a220a780ed12e7b4d51b3df032 upstream.
'cdev->os_desc_req' has been allocated with 'usb_ep_alloc_request()' so
'usb_ep_free_request()' should be used to free it.
