[PATCH] IB/hfi1: Delete an unnecessary check before the function call "sc_return_credits"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 23 Jul 2016 08:30:52 +0200

The sc_return_credits() 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.
