net: hsr: Add __packed to struct hsr_sup_tlv.

[ Upstream commit fbd825fcd7 ]

Struct hsr_sup_tlv describes HW layout and therefore it needs a __packed
attribute to ensure the compiler does not add any padding.
Due to the size and __packed attribute of the structs that use
hsr_sup_tlv it has no functional impact.

Add __packed to struct hsr_sup_tlv.
