shut up freezer_state

Not being able to get freezer state is perfectly valid - if the container does not exist. The old version of freezer_state only reported an error on actually reading the cgroup file, but not on not finding a cgroup file. Leave it to the caller to report the error if it is important, since we don't actually know any useful info here anyway. Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com>
