[PATCH] SCSI-libfc: Delete an unnecessary check before the function call "kmem_cache_destroy"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 16 Nov 2015 09:39:12 +0100

The kmem_cache_destroy() 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.
