Fix arch_prepare_kprobe() to handle failures in copy instruction correctly. This fix is related to the previous fix: 8101376 which made __copy_instruction return an error result if failed, but caller site was not updated to handle it. Thus, this is the other half of the bugfix. This fix is also related to the following bug-report: https://bugzilla.redhat.com/show_bug.cgi?id=910649 Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Tested-by: Jonathan Lebon <jlebon@redhat.com> Cc: Frank Ch.
