Justin Cormack 00c518411b Fix denial of service with large numbers in cpuset-cpus and cpuset-mems ...

Using a value such as `--cpuset-mems=1-9223372036854775807` would cause
`dockerd` to run out of memory allocating a map of the values in the
validation code. Set limits to the normal limit of the number of CPUs,
and improve the error handling.
