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.
