[libvirt] [PATCH] maint: Fix incorrect parenthesis placement causing true/false assignment

[Erik Skultety]

There were a few places in our code where the following pattern in 'if'
condition occurred:

if ((foo = bar() < 0))
    do something;

This patch adjusts the conditions to the expected format:

if ((foo = bar()) < 0)
    do something;

This can be especially "fun" if you try to assign multiple RNG devices to a
domain and then try to hot-unplug any of them but the first. Anyhow I used the
regex below to find these, I haven't spent much time tuning in, so in case
you can come up with a better one that yields more results like these I'm all
ears :).
