[PATCH] usb: gadget: udc-xilinx: compress return logic into one line

[Gustavo A. R. Silva]

Simplify return logic to avoid unnecessary variable assignment.

This issue was detected using Coccinelle and the following
semantic patch:

@@
local idexpression ret;
expression e;
@@

-ret =
+return
     e;
-return ret;
