mlx5: avoid truncating error message

clang warns that one error message is too long for its destination buffer:

drivers/net/ethernet/mellanox/mlx5/core/esw/bridge.c:1876:4: error: 'snprintf' will always be truncated; specified size is 80, but format string expands to at least 94 [-Werror,-Wformat-truncation-non-kprintf]

Reword it to be a bit shorter so it always fits.
