bridge: vlan: Use printf() to avoid temporary buffer

Browse Source 
Currently, print_vlan_tunnel_info() is first outputting a formatted string
to a temporary buffer in order to use print_string() which can handle json
or normal text mode. Since this specific string is only output in normal
text mode, by calling printf() directly, we can avoid the need to first
output to a temporary string buffer.
