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.
