eal/x86: fix pedantic build

Browse Source 
When enabling pedantic compilation with CONFIG_RTE_LIBRTE_MLX5_DEBUG,
the compiler complains about non standard 128-bit integer type:

include/rte_atomic_64.h:223:3: error:
ISO C does not support ‘__int128’ types [-Werror=pedantic]

It must be marked as an extension of the standard C language
to be accepted in pedantic compilation.

Fixes: 640c5f09ef2c ("eal/x86: add 128-bit atomic compare exchange")
