balloon: Separate out stat and balloon handling

Passing on '0' as ballooning target to indicate retrieval of stats is
bad API. It also makes 'balloon 0' in the monitor cause a segfault.
Have two different functions handle the different functionality instead....

balloon: Don't allow multiple balloon handler registrations

Multiple balloon devices don't make sense; disallow more than one
registration attempt to register handlers.

balloon: Make functions, local vars static

balloon.h had function declarations for a couple of functions that are
local to balloon.c. Make them static.

Drop the 'qemu_' prefix for balloon.c-local variables, and make them
static.
