Remove old stale expression_completer hack

Browse Source 
The code in question was introduced by:

 https://sourceware.com/ml/gdb-patches/2008-06/msg00143.html

"The fix is to make sure that the entire expression is passed to
expression_completer, then duplicate some logic there in the case
where location_completer is called."

The logic that was duplicated was much later on removed by the
original explicit locations patch:

 -                       ;
 -                   }

However this case in expression_completer was left behind.

I couldn't come up with a test where this currently makes any
difference.
