Fix Bug #58653 - Sporadic crash due to assertion failure 0 == space->n_pending_flushes

Check whether the master and purge thread are active after creating them. Do
not proceed until both threads have started. We do this by checking whether a
slot has been reserved by both the respective threads.
      
Add srv_thread_has_reserved_slot() returns slot no or ULINT_UNDEFINED.
