[9.20] fix: usr: Fix assertion failure when dumping recursing clients

Browse source 
Previously, if a new counter was added to the hashtable
while dumping recursing clients via the `rndc recursing`
command, and `fetches-per-zone` was enabled, an assertion
failure could occur. This has been fixed.

Closes #5200

Backport of MR !10164

Merge branch 'backport-5200-destroy-iterator-inside-the-rwlock-9.20' into 'bind-9.20'

See merge request isc-projects/bind9!10168
