Add recovery code for unsupported SFP+.

Before this commit:
  If an unsupported SFP module is inserted before booting, the driver attach
  failed and there was no way to recover form it without rebooting or
  detaching/reattaching driver (drvctl -d && drvctl -r pciN).

After this commit:
  We can automatically recover any time by replacing it with a supported
  module.
