net/mlx4_core: Return -EPROBE_DEFER when a VF is probed before PF is sufficiently initialized
In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).
Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.
Based upon a suggestion by Ben Hutchings <bhutchings@solarflare.com>
