qmp: remove frequent, chatty log

Browse Source 
In Kata, we are getting a *lot* of logs at runtime from QMP, in particular `read from QMP: xxxx`

Ideally we'd set this to only be visible for trace, but I did not see this working when adding a
V(7) check around these prints. To avoid filling journal with info that isn't useful, let's drop.

Fixes: #165
