mlx4_core: Add QP range reservation support
To allow allocating an aligned range of consecutive QP numbers, add an
interface to reserve an aligned range of QP numbers and have the QP
allocation function always take a QP number.
This will be used for RSS support in the mlx4_en Ethernet driver and
also potentially by IPoIB RSS support.
