net: fix build with pedantic

The following error popped when compiling with -pedantic:

In file included from
 drivers/net/mlx5/mlx5_flow_dv.c:28:0:
 include/rte_gre.h:20:2:
 error: type of bit-field 'res2' is a GCC  extension [-Werror=pedantic]
 uint16_t res2:4; /**< Reserved */

Fixing by adding the __extension__ attribute.

Fixes: 894f71a3805d ("net: add GRE header structure")
