x86/unwind: Show function name+offset in ORC error messages
Improve the warning messages to show the relevant function name+offset.
This makes it much easier to diagnose problems with the ORC metadata.
Before:
WARNING: can't dereference iret registers at ffff8801c5f17fe0 for ip ffffffff95f0d94b
After:
WARNING: can't dereference iret registers at ffff880178f5ffe0 for ip int3+0x5b/0x60
