[PATCH v2 1/3] crypto-ixp4xx: Delete unnecessary checks before the function call "dma_pool_destroy"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 15 Nov 2015 16:51:21 +0100

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

This issue was detected by using the Coccinelle software.
