f2fs: avoid clear valid page
In f2fs_delete_entry, if last dirent is remove from the dentry page, we will try to punch that page since it has no valid date in it. But truncate_hole which is used for punching could fail because of no memory or IO error, if that happened, we'd better skip clearing this valid dentry page.
