FRV: Fix no-hardware-breakpoint case
If there is no hardware breakpoint support, modify_user_hw_breakpoint() tries to return a NULL pointer through as an 'int' return value: In file included from kernel/exit.c:53: include/linux/hw_breakpoint.h: In function 'modify_user_hw_breakpoint': include/linux/hw_breakpoint.h:96: warning: return makes integer from pointer without a cast Return 0 instead.
