BUG/MINOR: net_helper: fix incomplete decoding in sample_conv_eth_vlan

sample_conv_eth_vlan() reads the VLAN TCI at area[idx + 2] without
ensuring there are enough bytes. The original condition 'idx + 4 < data'
breaks when there IS room for more data, leading to an incomplete read
when trying to decode a VLAN ID.

This can be backported where this converter was backported.
