[ Upstream commit 07c8434150f4eb0b65cae288721c8af1080fde17 ]
If a memory allocation fails within a 'usb_ep_alloc_request()' call, the
already allocated memory must be released.
Fix a mix-up in the code and free the correct requests.
Fixes: c52661d60f63 ("usb-gadget: Initial merge of target module for UASP + BOT")
