chg: dev: The nodefullname doesn't need a read lock to access .name

Browse source 
The qpznode->name is constant - assigned when the node is created
and it is immutable, so there's no reason to have it locked at all.

Merge branch 'ondrej/nodefullname-no-read-lock' into 'main'

See merge request isc-projects/bind9!10686
