vmdk: Clean up "Invalid extent lines" error message
vmdk_parse_extents() reports parse errors like this:
error_setg(errp, "Invalid extent lines:\n%s", p);
where p points to the beginning of the malformed line in the image
descriptor. This results in a multi-line error message
Invalid extent lines:
<first line that doesn't parse>
<remaining text that may or may not parse, if any>
Error messages should not have newlines embedded. Since the remaining
text is not helpful, we can simply report:
Invalid extent line: <first line that doesn't parse>
