[SPARK-14594][SPARKR] check execution return status code
## What changes were proposed in this pull request?
When JVM backend fails without going proper error handling (eg. process
crashed), the R error message could be ambiguous.
```
Error in if (returnStatus != 0) { : argument is of length zero
```
This change attempts to make it more clear (however, one would still need
to investigate why JVM fails)
## How was this patch tested?
