xen/balloon: Remove pr_info's and don't alter retry_count
In the past the retry_count (in other form of this code) was zero. Meaning retry forever. Do the same thing here without changing it to the value 16. Also remove some of the pr_info as there is no need to spam the user. Acked-by: Ian Campbell <Ian.Campbell@eu.citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
