lib/spinlock_debug.c: print owner on spinlock lockup
When SPIN_BUG_ON is triggered, the lock owner information is reported. But it is omitted when spinlock lockup is detected. This information is useful especially on the architectures which don't implement trigger_all_cpu_backtrace() that is called just after detecting lockup. So report it and also avoid message format duplication.
