Fixing a prior memory leak created a double-free error when destroying
the NVM sorage of a node. We have two situations where we want to
discard a nodes dytnamic memory:
1. When the node is being deleted at runtime. This causes release of
both dynamic memory and NVM storage.
2. During shutdown, we release dynamic memory only.
This patch ensures that after node deletion releases dynamic memory,
the pointers to it are cleared, avoiding a second free attempt.
