rigol-dg: free memory that was allocated by SCPI get routines 

The SCPI get routines may allocate memory for response data which
callers have to free after use.

Move an existing release call to an earlier location, to avoid leaking
memory when an error path is taken.

This addresses part of bug #1683.
