freebsd with flexible iflib nic queues

Async writes triggered by a self-healing IO may be issued before the pool finishes the process of initialization. This results in a NULL dereference of `spa->spa_dsl_pool` in vdev_queue_max_async_writes(). George Wilson recommended addressing this issue by initializing the passed `dsl_pool_t **` prior to dmu_objset_open_impl(). Since the caller is passing the `spa->spa_dsl_pool` this has the effect of ensuring it's initialized. However, since this depends on the caller knowing they must pass the `spa->spa_dsl_pool` an additional NULL check was added to vdev_queue_max_async_writes(). This guards against any future restructuring of the code which might result in dsl_pool_init() being called differently.
