[PATCH] InfiniBand: Delete unnecessary checks before the function, call "srp_destroy_fr_pool"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 5 Feb 2015 13:20:42 +0100

The srp_destroy_fr_pool() 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.
