LP:956427 - SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value

When SQL_ERROR_LOG plugin is installed, either at runtime or on server startup, it produces warnings:

[Warning] option 'sql-error-log-size-limit': unsigned value 0 adjusted to 100
[Warning] option 'plugin-sql-error-log-size-limit': unsigned value 0 adjusted to 100

These warnings are wrong: the default value of sql_error_log_size_limit is in fact 10000, and moreover, the warnings appear even if sql-error-log-size-limit is set explicitly upon startup.
