[PATCH -next] net/mlx5: Fix build error of multiple definition

[PATCH -next] net/mlx5: Fix build error of multiple definition

[Guan Jing]

There are some errors like:

drivers/net/ethernet/mellanox/mlx5/core/lag/lag.o:
In function `mlx5_lag_mpesw_init':
lag.c:(.text+0xb70): multiple definition of `mlx5_lag_mpesw_init'
drivers/net/ethernet/mellanox/mlx5/core/lag/debugfs.o:debugfs.c:(.text+0x440):
first defined here
drivers/net/ethernet/mellanox/mlx5/core/lag/lag.o: In function `mlx5_lag_mpesw_cleanup':
lag.c:(.text+0xb80): multiple definition of `mlx5_lag_mpesw_cleanup'
drivers/net/ethernet/mellanox/mlx5/core/lag/debugfs.o:debugfs.c:(.text+0x450):
first defined here

So, add 'static inline' on the defineation of these functions.
