net/mlx5: register memory event callback in Windows

In device initialization, the driver registers to free hugepages events.
When hugepage is released, this callback frees all its related MRs.

In Windows initialization, this callback is not registered what may
cause to use invalid memory.

This patch adds memory event callback registration in Windows
initialization.
