In the past we've seen multiple race conditions that have to do with open-context threads async threads and concurrent calls to spa_export()/spa_destroy() (including the one referenced in issue #9015). This patch ensures that only one thread can execute the main body of spa_export_common() at a time, with subsequent threads returning with a new error code created just for this situation, eliminating this way any race condition bugs introduced by concurrent calls to this function.
