kprobes: Fix arch_prepare_kprobe to handle copy insn failures
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:
