[PATCH libICE 1/3] Make sure errorStr is a free-able string

[Eric Engestrom]

If the `errorClass` isn't handled by the switch, `errorStr`'s initial
value would be a pointer to some static memory with an empty string,
and freeing it would most likely crash.

Let's set it to NULL instead, as is done in other similar places.
