ecpg: Refactor ecpg_log() to skip unnecessary calls to ECPGget_sqlca().

Browse Source 
Previously, ecpg_log() always called ECPGget_sqlca() to retrieve sqlca,
even though it was only needed for debug logging. This commit updates
ecpg_log() to call ECPGget_sqlca() only when debug logging is enabled.
