Improve vdsk_open():
1.  Use calloc(3) instead of malloc(3) so that the user context is
    always pre-initialized.
2.  Wrap the sequence of steps in a `do { ... } while (0)' block so
    that we can use break to exit. Introduce ctx as the variable to
    return and use it to determine success or failure.

With a single entry and a single exit, we can more easily add some
kind of tracing or logging in the future.
