kernel: mm/sparsemem: fix race in accessing memory_section->usage

A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. Thi...
