[PATCH] fix faulty inode data collection for open() with O_CREAT

Browse source 
When the specified path is an existing file or when it is a symlink, audit
collects the wrong inode number, which causes it to miss the open() event.
Adding a second hook to the open() path fixes this.

Also add audit_copy_inode() to consolidate some code.
