Fix: take RCU read-side lock within hash table functions
After review, a great deal of caller sites miss the RCU read-side lock
when using the hash table modification functions. This is a case where
having a slight performance degradation might be worthwhile if we can be
a bit more stability. So instead of playing whack-a-mole, add the RCU
read-side lock in the hash table modification functions to ensure
protection from ABA.

Applications using the liblttng-ctl library are most probably
