Small bug in rlm_sql_log

I discovered that if you use a file name like : path = ${radacctdir}/%Y/%m/sqlrelay-%Y%m%d You get an error if the path does not exist. A simple remedy is to configure auth_log to put files in the same directory, because it will create the directories. I will look into adding the functionality into this module to allow creation of the required directories but may not have time right away. TTFN
