atm: separate ATM_GETNAMES handling from the rest of atm_dev_ioctl()
atm_dev_ioctl() does copyin in two different ways - one for
ATM_GETNAMES, another for everything else. Start with separating
the former into a new helper (atm_getnames()). The next step
will be to lift the copyin into the callers.
