panic: Fix panic message visibility by calling bust_spinlocks(0) before dying
Commit ffd71da4e3f ("panic: decrease oops_in_progress only after having done the panic") moved bust_spinlocks(0) to the end of the function, which in practice is never reached. As a result console_unblank() is not called, and on some systems the user may not see the panic message. Move it back up to before the unblanking.
