Type: fix

| src/vppinfra/vector/toeplitz.c:69:9: error: ‘kv’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
| src/vppinfra/memcpy_x86_64.h:45:17: error: ‘*((void *)&key+16)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
|    *(u8x16u *) d = *(u8x16u *) s;
|    ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~
| src/vnet/gre/interface.c:356:20: note: ‘*((void *)&key+16)’ was declared here
