The check for NULL is not necessary before calling rte_rcu_qsbr_dq_delete.
Similar to other free routines, an error will not occur when the dq pointer is
NULL.
However, it will give a debug log statement to indicate an invalid parameter
and return 0 to indicate success.

Side note:
rte_rcu_qsbr_dq_delete should be changed to accept NULL as nop.
Like all the other free routines
