Fixed parameter parsing in change_device.php (#5559)

explode parses each parameter into more than just 2 parts, if the string contains more than one "=" character.

Can be fixed by limiting explode to output just two elements, then it automatically stops at the first "=" sign and keeps the rest of the string behind it untouched.
