Monitor.cmd_table contains the handlers for HMP commands, so there is no
reason to keep it in the state shared with QMP. Move it to MonitorHMP.

As far as I can tell, this is the only assignment to Monitor member
cmd_table.  Why not delete it outright, and use mon_cmds directly?
Preferably renamed to something like hmp_cmds.

Good idea, I'll do that.
