IMPALA-13771: Fix heap-use-after-free in Cluster Membership Manager
The ASAN tests identified a heap-use-after-free issue. This patch
fixes that issue by moving the memory release to after its last use.
Local execution of custom-cluster-mgr-test ASAN replicated the same
heap-use-after-free failure.
Testing:
Existing custom-cluster-mgr-test passed locally using debug build.
Existing custom-cluster-mgr-test passed locally using ASAN build.
