rmap: wrap page_check_address() using __cond_lock()
The page_check_address() conditionally grabs *@ptlp in case of returning
non-NULL. Rename and wrap it using __cond_lock() removes following
warnings from sparse:
mm/rmap.c:472:9: warning: context imbalance in 'page_mapped_in_vma' - unexpected unlock
mm/rmap.c:524:9: warning: context imbalance in 'page_referenced_one' - unexpected unlock
mm/rmap.c:706:9: warning: context imbalance in 'page_mkclean_one' - unexpected unlock
mm/rmap.c:1066:9: warning: context imbalance in 'try_to_unmap_one' - unexpected unlock
