[PATCH 2/2] x86: use sparse_memory_present_with_active_regions()on UMA

[Pekka Enberg]

From: Pekka Enberg <penberg@xxxxxxxxxxxxxx>

There's no need to use call memory_present() manually on UMA because
initmem_init() sets up early_node_map by calling
e820_register_active_regions().

[ Impact: cleanup ]
