Subject: drivers/usb/gadget/lpc32xx_udc.c: adjust inconsistent IS_ERR and PTR_ERR

drivers/usb/gadget/lpc32xx_udc.c: adjust inconsistent IS_ERR and PTR_ERR

Change the call to PTR_ERR to access the value just tested by IS_ERR.

The semantic match that finds this problem is as follows:

// <smpl>

expression e,e1;

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }

if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
 { ...
*  PTR_ERR(e1)
   ... }
)
// </smpl>
