ztest: ENOSPC in ztest_objset_destroy_cb()
While unlikely it is possible for dsl_destroy_head() to return
ENOSPC in the ztest_objset_destroy_cb(). This can occur even
when ZFS_SPACE_CHECK_DESTROY is used with the dsl_sync_task().
Both the existence of a checkpoint and pending deferred frees
can cause this.
