Subject: [PATCH] net/mlx5: Declare 'rt' as corresponding enum type

When building kernel with clang, we can observe below warning message:

drivers/net/ethernet/mellanox/mlx5/core/steering/dr_action.c:1080:9:
warning: implicit conversion from enumeration type 'enum mlx5_reformat_ctx_type'

Declare 'rt' as corresponding enum mlx5_reformat_ctx_type type.
