This patch fixes compilation errors with meson and the clang
compiler caused by some of the struct members not being
initialized.

```
../drivers/net/mlx4/mlx4_mr.c:357:37: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                struct mlx4_mr_cache entry = { 0, };
                                                  ^
../drivers/net/mlx4/mlx4_mr.c:401:36: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                        struct mlx4_mr_cache ret = { 0, };
                                                        ^
../drivers/net/mlx4/mlx4_mr.c:691:35: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                struct mlx4_mr_cache ret = { 0, };
                                                ^
```

The compilation errors reproduce with
clang version 3.4.2 (tags/RELEASE_34/dot2-final) on RHEL.
