Udipto Goswami bb03899b9b usb: gadget: f_fs: Ensure ep0req is dequeued before free_request 
[ Upstream commit ce405d561b020e5a46340eb5146805a625dcacee ]

As per the documentation, function usb_ep_free_request guarantees
the request will not be queued or no longer be re-queued (or
otherwise used). However, with the current implementation it
doesn't make sure that the request in ep0 isn't reused.

Fix this by dequeuing the ep0req on functionfs_unbind before
freeing the request to align with the definition.
