Btrfs: print btrfs specific info for some fatal error cases
Marc argued that if there are several btrfs filesystems mounted, while users even don't know which filesystem hit the corrupted errors something like generation verification failure. Since @extent_buffer structure has a member @fs_info, let's output btrfs device info.
