[gnome-db] PATCH: Fix return value for gda_drop_table()

[Phil Longstaff <plongstaff rogers com>]

The convenience function gda_drop_table() returns the wrong value.  
First, there are braces missing on an if-then-else, so that even if the 
operation is successful, the error path is taken.  Secondly, 
gda_server_provider_perform_operation() returns TRUE if the operation 
has no error, so the sense of the test needs to be reversed.

I've attached a patch to the libgda 3.0.2 source to fix these problems.
