mlx4_core: Make buffer larger to avoid overflow warning
My static checker complains that the sprintf() here can overflow.
drivers/infiniband/hw/mlx4/main.c:1836 mlx4_ib_alloc_eqs()
error: format string overflow. buf_size: 32 length: 69
This seems like a valid complaint. The "dev->pdev->bus->name" string
can be 48 characters long. I just made the buffer 80 characters instead
of 69 and I changed the sprintf() to snprintf().
