vfs: add vfs_get_link() helper
This helper is for filesystems that want to read the symlink and are better off with the get_link() interface (returning a char *) rather than the readlink() interface (copy into a userspace buffer). Also call the LSM hook for readlink (not get_link) since this is for symlink reading not following. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
