page-allocator: clear N_HIGH_MEMORY map before we set it again
SRAT tables may contains nodes of very small size. The arch code may
decide to not activate such a node. However, currently the early boot
code sets N_HIGH_MEMORY for such nodes. These nodes therefore seem to be
active although these nodes have no present pages.
For 64bit N_HIGH_MEMORY == N_NORMAL_MEMORY, so that works for 64 bit too
