[PATCH 2/7] drivers/usb/gadget: Remove double test

[Julia Lawall <julia@diku.dk>]

The same expression is tested twice and the result is the same each time.

The sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@expression@
expression E;
@@

(
* E
  || ... || E
|
* E
  && ... && E
)
// </smpl>

Signed-off-by: Julia Lawall <julia@diku.dk>

This is a guess as to what the code should be.  Perhaps something else
should have been tested instead.
