Previously, mlx4_en allocated EQs and used them exclusively.
This affected RoCE performance, as applications which are
events sensitive were limited to use only the legacy EQs.
Change that by introducing an EQ pool. This pool is managed
by mlx4_core. EQs are

When freeing a CQ, we need to make sure there are no
asynchronous events (on the ASYNC EQ) that could
relate to this CQ before freeing it.
This is done by introducing synchronize_irq.

In SRIOV, when simple (i.e - Ethernet L2 only) flow steering rules are
created, always create them at MLX4_DOMAIN_NIC priority (instead of
the real priority the function created them at). This is done in order
to let multiple functions add broadcast/multicast

Now that EQs management is in the sole responsibility of mlx4_core,
the IRQ affinity hints configuration should be in its hands as well.
request_irq is called only once by the first consumer (maybe mlx4_ib),
so mlx4_en passes the affinity mask too late. We also
