NetLabel: return the correct error for translated CIPSOv4 tags
The CIPSOv4 translated tag #1 mapping does not always return the correct error code if the desired mapping does not exist; instead of returning -EPERM it returns -ENOSPC indicating that the buffer is not large enough to hold the translated value. This was caused by failing to check a specific error condition. This patch fixes this so that unknown mappings return -EPERM which is consistent with the rest of the related CIPSOv4 code.
