QMP: Drop the query commands dispatch table

Because QMP development originated in the monitor, it has
inherited the monitor's distinction between query- and
non-query commands.

However, previous commits unified both commands and the
distinction is gone. This commit drops the query commands
dispatch table and does some simplifications along the way.
