[RFC PATCH 3/6] perf tools: Add disassembly warnings for annotate --stdio

[James Clark]

Currently 'perf annotate --stdio' (and --stdio2) will exit without
printing anything if there are disassembly errors. Apply the same
error handler that's used for TUI and GTK modes. This makes comparing
disassembly across the different modes more consistent.
