vmalloc: export __vmalloc_node_range for CONFIG_TEST_VMALLOC_MODULE

Export __vmaloc_node_range() function if CONFIG_TEST_VMALLOC_MODULE is
enabled.  Some test cases in vmalloc test suite module require and make
use of that function.  Please note, that it is not supposed to be used
for other purposes.

We need it only for performance analysis, stressing and stability check
of vmalloc allocator.
