Restore dirty dnode detection logic

Browse Source 
In addition to flushing memory mapped regions when checking holes,
commit de198f2d95 modified the dirty dnode detection logic to check
the dn->dn_dirty_records instead of the dn->dn_dirty_link.  Relying
on the dirty record has not be reliable, switch back to the previous
method.
