Free hashtable prior to freeing atomic worker_lock

Free hashtable prior to freeing atomic worker_lock

lhash_test uses a hashtable that may not be empty at the end of the test

Given that the free function frees the elements in the list and uses the
atomic worker_lock to do so, we need to free the hash table prior to
freeing the working lock to avoid the use of unallocated memory.

Fixes #26798
