When there're mutiple EEH errors, we need serialize the process to keep consistent PE state (flags). The spinlock "confirm_error_lock" was introduced for the purpose. We'll inject EEH event upon error reporting interrupts on PowerNV platform. So we export the spinlock for that to use for consistent PE state.
