net/mlx5: fix pre-2.40 binutils assembler error 

Old binutils versions require a slightly stricter syntax for the .arch_extension
directive and fail with the extra semicolon:

/tmp/cclfMnj9.s:656: Error: unknown architectural extension `simd;'

Drop the semicolon to make it work with all supported toolchain version.
