[libvirt] [PATCH 1/2] BlockJob: Bandwidth parameter is in MB when using text monitor

Due to an unfortunate precedent in qemu, the units for the bandwidth parameter
to block_job_set_speed are different between the text monitor and the qmp
monitor.  While the qmp monitor uses bytes/s, the text monitor expects MB/s.

Correct the units for the text interface.
