Andriy Gapon 8605a08bd2 MFV r322227: 8377 Panic in bookmark deletion
illumos/illumos-gate@42418f9e73

https://www.illumos.org/issues/8377
  The problem is that when dsl_bookmark_destroy_check() is executed from open
  context (the pre-check), it fills in dbda_success based on the existence of the
  bookmark.
  But the bookmark (or containing filesystem as in this case) can be destroyed
  before we get to syncing context. When we re-run dsl_bookmark_destroy_check()
  in syncing
  context, it will not add the deleted bookmark to dbda_success, intending for
  dsl_bookmark_destroy_sync() to not process it. But because the bookmark is
  still in dbda_success
  from the open-context call, we do try to destroy it.
  The fix is that dsl_bookmark_destroy_check() should not modify dbda_success
  when called from open context.
