[libvirt] [PATCH] qemu: Resolve Coverity UNINIT

For some reason, commit id '72b4151f' triggered a Coverity uninitialized
'reply' variable check when referenced within the for loop.

It seems Coverity doesn't know that flags will have to be either AFFECT_LIVE
or AFFECT_CONFIG after the virDomainLiveConfigHelperMethod call.

By adding a "sa_assert()" to confirm that fact, Coverity is happy again.

Signed-off-by: John Ferlan <jferlan redhat com>

 did not clear the error - only the two separate checks using the ||.

 Yes, the parentheses are overkill...
