IB/core: Add legacy driver's user-data
In this phase, we don't want to change all the drivers to use flexible driver's specific attributes. Therefore, we add two default attributes: UHW_IN and UHW_OUT. These attributes are optional in some methods and they encode the driver specific command data. We add a function that extract this data and creates the legacy udata over it. Driver's data should start from UVERBS_UDATA_DRIVER_DATA_FLAG. This turns on the first bit of the namespace, indicating this attribute belongs to the driver's namespace.
