[libvirt PATCH] conf: node_device: use separate variable for parsing an integer

[Ján Tomko <jtomko@xxxxxxxxxx>]

In virNodeDeviceGetSCSIHostCaps, there is a pattern of reusing
a tmp value and stealing the pointer.

But in one case it is not stolen. Use a separate variable for it
to avoid mixing autofree with manual free() calls.
