tools/testing/scatterlist: add missing defines
The cited commits replaced preemptible with pagefault_disabled and
flush_kernel_dcache_page with flush_dcache_page respectively, hence need
to update the corresponding defines in the test.
scatterlist.c: In function ‘sg_miter_stop’:
scatterlist.c:919:4: warning: implicit declaration of function ‘flush_dcache_page’ [-Wimplicit-function-declaration]
flush_dcache_page(miter->page);
^~~~~~~~~~~~~~~~~
In file included from linux/scatterlist.h:8:0,
from scatterlist.c:9:
scatterlist.c:922:18: warning: implicit declaration of function ‘pagefault_disabled’ [-Wimplicit-function-declaration]
WARN_ON_ONCE(!pagefault_disabled());
^
linux/mm.h:23:25: note: in definition of macro ‘WARN_ON_ONCE’
int __ret_warn_on = !!(condition); \
