Subject: [PATCH 4/9] mlx5: avoid truncating error message

From: Arnd Bergmann <arnd@...db.de>

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.

Fixes: 70f0302b3f20 ("net/mlx5: Bridge, implement mdb offload")
