memblock tests: fix undefined reference to `early_pfn_to_nid'

RichardWeiYang · rppt · commit 7d8ed162e6a9 · 2024-04-04T11:08:32.000+03:00
commit 6a9531c ("memblock: fix crash when reserved memory is not added to memory") introduce the usage of early_pfn_to_nid, which is not defined in memblock tests. The original definition of early_pfn_to_nid is defined in mm.h, so let add this in the corresponding mm.h.
