hv_balloon: disable warning when floor reached

Browse source 
[ Upstream commit 2c3bd2a5c86fe744e8377733c5e511a5ca1e14f5 ]

It is not an error if the host requests to balloon down, but the VM
refuses to do so. Without this change a warning is logged in dmesg
every five minutes.

Fixes:  b3bb97b8a4 ("Drivers: hv: balloon: Add logging for dynamic memory operations")
