Tianyu Lan e6c92036c2 hv_balloon: Balloon up according to request page number 
commit d33c240d47dab4fd15123d9e73fc8810cbc6ed6a upstream.

Current code has assumption that balloon request memory size aligns
with 2MB. But actually Hyper-V doesn't guarantee such alignment. When
balloon driver receives non-aligned balloon request, it produces warning
and balloon up more memory than requested in order to keep 2MB alignment.
Remove the warning and balloon up memory according to actual requested
memory size.

Fixes: f671223847 ("hv: hv_balloon: avoid memory leak on alloc_error of 2MB memory block")
