[libvirt PATCH v2 6/6] virDomainAudioSDLParse: Use virXMLProp*

[Tim Wiederhake <twiederh@xxxxxxxxxx>]

This strictens the parser to disallow negative values (interpreted as
`UINT_MAX + value + 1`) for attribute `bufferCount`.

`bufferCount` does not benefit from being referable as e.g. "-7" for
requesting 4294967289 buffers, as this value is distinctly out of range
for normal use.
