Minor: determine the `functionName` first in an if/else if/else block, and 
create the command afterwards. This saves some duplication.

[SPARK-14910] [SQL] Native DDL Command Support for Describe Function in 
Non-identifier Format

 What changes were proposed in this pull request?
The existing `Describe Function` only support the function name in 
`identifier`. This is different from what Hive behaves. That is why many test 
cases `udf_abc` in `HiveCompatibilitySuite` do not pass. For example, 
- udf_not.q
- udf_bitwise_not.q

This PR is to resolve the issues. Now, we can support the command of 
`Describe Function` whose function names are in the following format:
- `qualifiedName` (e.g., `db.func1`)
- `STRING` (e.g., `'func1'`)
- `comparisonOperator` (e.g,. `<`)
- `arithmeticOperator` (e.g., `+`)
- `predicateOperator` (e.g., `or`)

Note, before this PR, we only have a native command support when the 
function name is in the format of `qualifiedName`.
 How was this patch tested?
Added test cases in `DDLSuite.scala`. Also manually verified all the 
related test cases in `HiveCompatibilitySuite` passed.

You can merge this pull request into a Git repository by running:

$ git pull https://github.com/gatorsmile/spark descFunction

Alternatively you can review and apply these changes as the patch at:
