Database: Ensure that variables are defined correctly.
There were some cases where some local variables in `wpdb::init_charset()` could be undefined when they were used. Props Frozzare. Fixes #37683 for trunk. Built from https://develop.svn.wordpress.org/trunk@38439 git-svn-id: http://core.svn.wordpress.org/trunk@38380 1a063a9b-81f0-0310-95a4-ce76da25c4cd
