extent scan: don't serialize dedupe and LOGICAL_INO when using extent scan mode

Browse Source 
The serialization doesn't seem to be necessary for the extent scan mode.
No infinite loops in the kernel have been observed in the past two years,
despite never having used MultiLock for the extent scanner.

Leave the serialization for now on the subvol scanners.
