mm/swap: make NODE_DATA an inline function on CONFIG_FLATMEM
make W=1 generates the following warning in mm/workingset.c for allnoconfig
mm/workingset.c: In function `unpack_shadow':
mm/workingset.c:201:15: warning: variable `nid' set but not used [-Wunused-but-set-variable]
int memcgid, nid;
^~~
On FLATMEM, NODE_DATA returns a global pglist_data without dereferencing
nid. Make the helper an inline function to suppress the warning, add type
checking and to apply any side-effects in the parameter list.
