mlx4_core: Fix advertisement of wrong PF context behaviour
Commit 08ff32352d6f ("mlx4: 64-byte CQE/EQE support") introduced a
regression where older guest VF drivers failed to load even when
64-byte EQEs/CQEs are disabled, since the PF wrongly advertises the
new context behaviour anyway. The failure looks like:
mlx4_core 0000:00:07.0: Unknown pf context behaviour
mlx4_core 0000:00:07.0: Failed to obtain slave caps
mlx4_core: probe of 0000:00:07.0 failed with error -38
Fix this by basing this advertisement on dev->caps.flags, which is the
operational capabilities used by the QUERY_FUNC_CAP command wrapper
(dev_cap->flags holds the firmware capabilities).
