[PATCH 1/1] GFS2: Deletion of unnecessary checks before two function calls

From: Markus Elfring <elfring@users.sourceforge.net>

The functions iput() and put_pid() test whether their argument is NULL
and then return immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
