#1704957 — [PATCH 3/5] Drivers: hv: balloon: Show the max dynamic memory assigned

From: Alex Ng <alexng@messages.microsoft.com>

Previously we were only showing max number of pages. We should make it
more clear that this value is the max amount of dynamic memory that the
Hyper-V host is willing to assign to this guest.
