ocfs2: delete unnecessary checks before three function calls

Browse Source 
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.
