[PATCH] USB: whci-hcd: Delete an unnecessary check before the function call "usb_put_hcd"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 5 Feb 2015 16:54:12 +0100

The usb_put_hcd() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
