debug_core,kdb: fix crash when arch does not have single step When an arch such as mips and microblaze does not implement either HW or software single stepping the debug core should re-enter kdb. The kdb code will properly ignore the single step operation. Attempting to single step the kernel without software or hardware support causes unpredictable kernel crashes.
