net: hsr: require valid EOT supervision TLV
Supervision frames are only valid if terminated with a zero-length EOT
TLV. The current check fails to reject non-EOT entries as the terminal
TLV, potentially allowing malformed supervision traffic.
Fix this by strictly requiring the terminal TLV to be HSR_TLV_EOT with
a length of zero.
