Remove called_from argument from kprobes which had been used for
preventing self-refering of kernel module. However, since we don't keep
module's refcount after registering kprobe any more, there is no reason to
check that.
This patch also simplifies registering/unregistering functions because we
don't need to use __builtin_return_address(0) which was passed to
called_from.
