Oleg Nesterov 90718e32e1 uprobes/x86: Remove incorrect WARN_ON() in uprobe_init_insn() ...

insn_get_length() has the side-effect of processing the entire instruction
but only if it was decoded successfully, otherwise insn_complete() can fail
and in this case we need to just return an error without warning.
