This patch changes the interface to allow that. It also changes the way the UMR operation validates the memory region's state. When set, IB_SEND_UMR_FAIL_IF_FREE will cause the UMR operation to fail if the MKEY is in the free state. When it is unchecked the operation will check that it isn't in the free state.
