[libvirt] [PATCH] Disable use of 'reason' field in block IO event in QEMU

["Daniel P. Berrange" <berrange redhat com>]

QEMU upstream decided against adding a 'reason' field to
the block IO event in QMP. Disable this code to remove a
annoying warning message. It will be renabled when the
error string reason is re-introduced in QEMU
