vlib: fix the total len not including first buffer formating

Browse Source 
Type: fix

total len not including first buffer is in vlib_buffer_t second cacheline.
It is not reset after the buffer has been consumed. It leads to printing
garbage in packet trace for subsequent use of this buffer. This patch
fixes the issue to only print when VLIB_BUFFER_NEXT_PRESENT flag is set.
