hmp: Update current monitor only in handle_hmp_command()

Browse source 
The current monitor is updated relatively early in the command handling
code even though only the command handler actually needs it.

The current monitor will become coroutine-local later, so we can only
update it when we know in which coroutine the command will be exectued.
Move it to handle_hmp_command() where this information will be
available.
