Making some changes designed to not allow for a corrupted mailstream for a vm_state.

1. Add locking to the vm_state retrieval functions so that no linked list corruption occurs.
2. Make sure to always grab the persistent vm_state when mailstream access is necessary.
3. Correct an incorrect return value in the init_mailstream function.

(closes issue #11304, reported by dwhite)
