[PATCH 02/10] mm/madvise: name the shared LRU PMD callback

[Gregory Price]

The MADV_COLD and MADV_PAGEOUT page-walk callback is named after its PTE
implementation even though it is registered as a PMD callback and serves
both LRU operations.

Rename it to madvise_lru_pmd_entry() before separating the PMD and PTE
paths.

No functional change intended.
