[PATCH 10/12] virSecurityDeviceLabelDefParseXML: Don't use 'virXPathStringLimit'

[Peter Krempa <pkrempa@xxxxxxxxxx>]

virXPathStringLimit doesn't give callers a way to differentiate between
the queried XPath being empty and the length limit being exceeded.

This means that the callers is completely ignoring the error.

Move the length check into the caller.
