[PATCH] net/mlx5: fix compilation issue in debug mode

[Adrien Mazarguil <adrien.mazarguil@6wind.com>]

Even in C11, using types other than _Bool or signed/unsigned int for
bit-fields is an extension. Some GCC versions complain about that when
-pedantic checks are enabled.

The RTE_STD_C11 macro correctly prevented this issue with C99 but not with
C11 as it becomes a no-op. Forcing the extension keyword addresses it.

Fixes: 143c03925695 ("net/mlx: update C compliance standard")

Ferruh, squashing this commit with the previous one and discarding its
log is fine if you want. Thanks.
