net/mlx5e: Reduce the size of icosq_str

icosq_str size is unnecessarily too long, and it causes a build warning
-Wformat-truncation with W=1. Looking closely, It doesn't need to be 255B,
hence this patch reduces the size to 32B which should be more than enough
to host the string: "ICOSQ: 0x%x, ".

While here, add a missing space in the formatted string.

This fixes the following build warning:

$ KCFLAGS='-Wall -Werror'
$ make O=/tmp/kbuild/linux W=1 -s -j12 drivers/net/ethernet/mellanox/mlx5/core/
