There's no way to error: now w/o @localAddr, @remoteAddr, & @subject
being allocated, thus there's no need to check whether they're non-null
before accessing.

There's no way to error: now w/o @localAddr, @remoteAddr, & @subject
being allocated, thus there's no need to check whether they're non-null
before accessing.
Actually, there's no way to error at all - VIR_REALLOC_N aborts on OOM.
I don't think it's worth deleting in the meantime.
