[libvirt] [PATCH] qemu: Don't overwrite stats in qemuDomainBlocksStatsGather

[Peter Krempa]

The size/capacity stats gathered in qemuDomainBlocksStatsGather when
using -blockdev would be overwritten by assigning/copying the transfered
data statistics at the end. Fix it by moving the assignment prior to
fetching the capacity data.
