l4p/tcp: fix SIGSEGV when reading IPv6 address
IPv6 address is obtained through pointer to mbuf (part storing IPv6 addr). Structure which then holds that pointer defines it as a pointer to _m128i data type. Because of that, when code is optimized, instruction vmovdqa is used, which requires data to be aligned to 16-bytes. Pointer from mbuf does not have to be aligned in that way, which may cause SIGSEGV. Solution is to add attribute packed and aligned(1) to structure holding IPv6 address. With that, vmovdqu assembly instruction is used, which is the equivalent of vmovdqa, but for unaligned data.
