[PATCH RFC 01/15] memory: Drop mapping check from memory_region_get_ram_discard_manager()

[David Hildenbrand <david@xxxxxxxxxx>]

It's sufficient to check whether a memory region is RAM, the region
doesn't necessarily have to be mapped into another memory region.
For example, RAM memory regions mapped via an alias will never make
"memory_region_is_mapped()" succeed.
