perf annotate: Add disassembly warnings for annotate --stdio

mainline inclusion
from mainline-v5.14-rc4
commit 243c3a3e
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I636PS
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=243c3a3eb4e03201dec36f2edfc4fe604d8b9078

--------------------------------------------------------------------------

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.
