Gavrilov Ilia 04bf69e3de ipv6: Fix out-of-bounds access in ipv6_find_tlv() 
commit 878ecb0897 upstream.

optlen is fetched without checking whether there is more than one byte to parse.
It can lead to out-of-bounds access.

Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

Fixes: c61a404325 ("[IPV6]: Find option offset by type.")
