mm: fix build of split ptlock code
Commit 597d795a2a78 ('mm: do not allocate page->ptl dynamically, if
spinlock_t fits to long') restructures some allocators that are compiled
even if USE_SPLIT_PTLOCKS arn't used. It results in compilation
failure:
mm/memory.c:4282:6: error: 'struct page' has no member named 'ptl'
mm/memory.c:4288:12: error: 'struct page' has no member named 'ptl'
Add in the missing ifdef.
Fixes: 597d795a2a78 ('mm: do not allocate page->ptl dynamically, if spinlock_t fits to long')
