[SPARK-19840][SQL] Disallow creating permanent functions with invalid class
names
## What changes were proposed in this pull request?
Currently, Spark raises exceptions on creating invalid **temporary**
functions, but doesn't for creating **permanent** functions. This PR aims to
disallow creating permanent functions with invalid class names.
**BEFORE**
```scala
scala> sql("CREATE TEMPORARY FUNCTION function_with_invalid_classname AS
'org.invalid'").show
java.lang.ClassNotFoundException: org.invalid at
...
scala> sql("CREATE FUNCTION function_with_invalid_classname AS
'org.invalid'").show
++
||
++
++
```
**AFTER**
```scala
scala> sql("CREATE FUNCTION function_with_invalid_classname AS
'org.invalid'").show
java.lang.ClassNotFoundException: org.invalid
```
## How was this patch tested?
Pass Jenkins tests with a new test case.
