History
Evan Hunt 03183baa6d Prevent a possible race in dns_qpmulti_query() and _snapshot() 
The `.reader` member of dns_qpmulti_t was accessed without RCU
protection; reader_open() calls rcu_dereference() on it, and this
call needs to be inside an RCU critical section.

A similar problem was identified in the dns_qpmulti_snapshot() - the
RCU critical section was completely missing.

These are relicts of the isc_qsbr - in the QSBR mode the rcu_read_lock()
and rcu_read_unlock() are no-ops and whole event loop is a critical section.
