mlx4_core: Reduce number of PD bits to 17
When SRIOV is enabled on the chip (at FW burning time),
the HCA uses only 17 bits for the PD. The remaining 7 high-order bits
are ignored.
Change the allocator to return only 17 bits for the PD. The MSB 7
bits will be used to encode the slave number for consistency
checking later on in the resource tracker.
