Be sure a CPU a device is attached to is present in the LPAR

When a device is attached to a LPAR, there is no guarantee that the CPU this device is attached to will be part of the LPAR. This leads to device with no specific numa node, confusing script managing irqbalancing like the Mellanox one and probably not provide best access performance.

The only way to workaround this with no guarantee of success is to prioritize the LPAR creation, but there is no guarantee for this to succeed and no error reported if this can be achieved.

When creating a LPAR, and adding devices to this LPAR, the user should be able to specify if a device is really important and that a CPU this device is attached to should be part of the LPAR.
