Variable 'ret' is set to the rerurn value of function
mlx5_mr_cache_alloc() but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed
Clean up the following clang-analyzer warning:
drivers/infiniband/hw/mlx5/odp.c:421:2: warning: Value stored to 'ret'
is never read [clang-analyzer-deadcode.DeadStores]
