ocfs2: delete unnecessary checks before three function calls
Author: Markus Elfring <elfring@users.sourceforge.net>
kfree(), ocfs2_free_path() and __ocfs2_free_slot_info() 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.
