net: hsr: fix potential OOB access in supervision frame handling

In the Linux kernel, the following vulnerability has been resolved:

net: hsr: fix potential OOB access in supervision frame handling

Ensure the entire TLV header is linearized before access by adding
sizeof(struct hsr_sup_tlv) to the pskb_may_pull() calls. Without this,
a truncated frame could cause an out-of-bounds access.
