add a helper function to test if an object is on the stack
lib/debugobjects.c has a function to test if an object is on the stack.
The block layer and ide needs it (they need to avoid DMA from/to stack
buffers). This patch moves the function to include/linux/sched.h so that
everyone can use it.
lib/debugobjects.c uses current->stack but this patch uses a
task_stack_page() accessor, which is a preferable way to access the stack.
