The QMP monitor only uses a newline to separate lines,
while HMP and the guest agent also use a carriage return.

In preparation to dropping support for testing HMP interaction,
only skip the carriage return if we're dealing with the guest agent,
removing the need to check the 'json' field.

Couple of things happening in this patch:

1) We can mark the device we're adding onto active list as used
   way before - when adding it onto temporary list.

2) When actually moving device from a temporary helper list onto
   the list of active devices we check if the device isn't
   already there. The same check is performed by
   virSCSIVHostDeviceListAdd() later. Drop this duplicity.

3) The 'error' label is renamed to 'rollback' to reflect what it
   is actually doing. While in the rest of the code we don't
   allow random label names, this source file is different.

the 'file' block backend supports dynamic auto-read-only.

Note that I've rebuilt this on a machine with a more modern kernel and
microcode which exposes e.g. the recent CPU bug mitigations, thus I
opted to keep the CPU changes rather than trying to do a franken-caps
