usb: gadget: loopback: Fix looping back logic implementation
Since commit e0857ce58e8658657f5f12fe25272b93cfeb16aa
("usb: gadget: loopback: don't queue requests to bogus endpoints")
Loopback function is not realy working as that commit removed
all looping back logic. After that commit ep-out works like
/dev/null and ep-in works like /dev/zero.
This commit fix this issue by allocating set of out requests
and set of in requests but each out req shares buffer with
one in req:
out_req->buf ---> buf <--- in_req.buf
out_req->context <---> in_req.context
The completion routine simply enqueue the suitable req in
an oposite direction.
