Subject: [PATCH 2/2] Remove unnecessary SQL mode check from wp db query
 command

This check was causing authentication failures when custom connection
parameters (like --host) were passed, because get_current_sql_modes()
ignored those parameters. The check is also unnecessary since wp db query
doesn't use WPDB directly, and was inconsistently applied (skipped for STDIN).
