O-Subject:  [RHEL-7.5 ovmf PATCH 1/1] MdeModulePkg/Core/Dxe: log informative
	memprotect msgs at DEBUG_INFO level
Bugzilla: 1520485

In commit 7eb927db3e25 ("MdeModulePkg/DxeCore: implement memory protection
policy", 2017-02-24), we added two informative messages with the
InitializeDxeNxMemoryProtectionPolicy() function:

> InitializeDxeNxMemoryProtectionPolicy: applying strict permissions to
> active memory regions

and

> InitializeDxeNxMemoryProtectionPolicy: applying strict permissions to
> inactive memory regions

The messages don't report errors or warnings, thus downgrade their log
masks from DEBUG_ERROR to DEBUG_INFO.
