Restore dirty dnode detection logic

In addition to flushing memory mapped regions when checking holes, commit de198f2 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. Signed-off-by: Brian Behlendorf <[email protected]> Issue openzfs#11900 Closes openzfs#12745
