The db_dirtycnt of an EVICTING dbuf is always 0. However, it still appears in the dn_dbufs tree. If we call dnode_dirty_l1range on a range that contains an EVICTING dbuf, we will attempt to mark it dirty (which will fail because it's EVICTING, resulting in a new dbuf being created and dirtied). Later, in ZFS_DEBUG mode, we assert that all the dbufs in the range are dirty. If the EVICTING dbuf is still present, this will trip the assertion erroneously.
