[libvirt] [PATCH 2/9] qemu: process: Don't try to redetect missing qemuCaps on reconnect

[Peter Krempa]

The redetection was originally added in 43c01d3838 as a way to recover
from libvirtd upgrade from the time when we didn't persist the qemu
capabilities in the status XML. Also this the oldest supported qemu by
more than two years.

Even if somebody would have a running VM running at least qemu 1.5 with
such an old libvirt we certainly wouldn't do the right thing by
redetecting the capabilities and then trying to communicate with qemu.

For now it will be the best to just stop considering this scenario any
more.
