Fix an integer overflow in get_ssh_string.

If the length field in the input data was so large that adding 4 to it
caused wraparound, the error check could fail to trigger. Fortunately,
this praticular get_ssh_string function is only used during private
key import from foreign file formats, so it won't be facing hostile
data.
