ocfs2: fix NULL pointer dereference in ocfs2_duplicate_clusters_by_page
Since ocfs2_cow_file_pos will invoke ocfs2_refcount_icow with a NULL as the struct file pointer, it finally result in a null pointer dereference in ocfs2_duplicate_clusters_by_page. This patch replace file pointer with inode pointer in cow_duplicate_clusters to fix this issue.
