[LU-3831] ll_readdir() ignores O_NOATIME

Description

ll_readdir calls touch_atime() which is wrong because it ignores
whether O_NOATIME is set in f_flags. On RHEL 6, this is moreover unnecessary as vfs_readdir() calls file_accessed() (which does check for O_NOATIME) after invoking f_op->readdir().
