[ Upstream commit d55510527153d17a3af8cc2df69c04f95ae1350d ]

tools/testing/cxl/test/mem.c uses vmalloc() and vfree() but does not
include linux/vmalloc.h. Kernel v6.10 made changes that causes the
currently included headers not depend on vmalloc.h and therefore
mem.c can no longer compile. Add linux/vmalloc.h to fix compile
issue.
