IMPALA-8612: Fix sporadic NPE when dropping an authorized table

In the analyze() function of DropTableOrViewStmt it's possible that
serverName_ is not set when analyzer.getTable() throws. As a result
when the Catalog executes the drop table DDL it runs into a failing
Precondition check and throws a NullPointerException when updating
user privileges. Note, to run into the NPE it's required to have
authorization enabled.
