Subject: [PATCH] usb: gadget: f_tcm: Fix some resource leaks in some error paths
Git-commit: 07c8434150f4eb0b65cae288721c8af1080fde17
Patch-mainline: v5.9-rc3
References: git-fixes

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.
