net/mlx5: Eliminate query xsrq dead code

Browse source 
1. This function is not used anywhere in mlx5 driver
2. It has a memcpy statement that makes no sense and produces build
warning with gcc8

drivers/net/ethernet/mellanox/mlx5/core/transobj.c: In function 'mlx5_core_query_xsrq':
drivers/net/ethernet/mellanox/mlx5/core/transobj.c:347:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict]

Fixes: 01949d0109 ("net/mlx5_core: Enable XRCs and SRQs when using ISSI > 0")
