[PATCH 1/1] lustre: Deletion of unnecessary checks before three function calls

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 2 Dec 2014 11:40:33 +0100

The functions free_ll_remote_perm(), free_rmtperm_hash() and iput() test
whether their argument is NULL and then return immediately.
Thus the test around their calls is not needed.

This issue was detected by using the Coccinelle software.
