ruby_debug_log: suppress warning

Browse source 
Old gcc (< 5 maybe?) warns that this variable is not initialized:

    debug.c: In function 'ruby_debug_log':
    debug.c:441:13: warning: 'r' may be used uninitialized in this function [-Wmaybe-uninitialized]
             if (r && len < MAX_DEBUG_LOG_MESSAGE_LEN) {
                 ^

I don't know if that is true, but adding "= 0" here must harm no one.
