Description

To reproduce:

0: jdbc:drill:drillbit=localhost> use dfs;
+-------+----------------------------------+
|  ok   |             summary              |
+-------+----------------------------------+
| true  | Default schema changed to [dfs]  |
+-------+----------------------------------+
1 row selected (0.849 seconds)
0: jdbc:drill:drillbit=localhost> describe schema tmp;
Error: SYSTEM ERROR: NullPointerException;

  Caused By (java.lang.NullPointerException) null
    org.apache.drill.exec.planner.sql.handlers.DescribeSchemaHandler.getPlan():84

The root cause is that we try to retrieve storage config by workspace name but by not actual schema name.
