Marius Strobl ec3e6e77a1 - Send the RELSIM_ADJUST_OPENINGS in response to a MPI_EVENT_QUEUE_FULL using
the right SIM in case the HBA is RAID-capable but the target in question is
  not a hot spare or member of a RAID volume.
- Report the loss and addition of SAS and SATA targets detected via PHY link
  status changes and signalled by MPI_EVENT_SAS_DEVICE_STATUS_CHANGE to cam(4)
  as lost devices and trigger rescans as appropriate. Without this it can take
  quite some time until a lost device actually is no longer tried to be used,
  if it ever stops. [1]
- Handle MPI_EVENT_IR2, MPI_EVENT_LOG_ENTRY_ADDED, MPI_EVENT_SAS_DISCOVERY
  and MPI_EVENT_SAS_PHY_LINK_STATUS silently as these serve no additional
  purpose beyond adding cryptic entries to logs.

Thanks to Hans-Joerg Sirtl for providing one of the HBAs these changes were
developed with and RIP to the mainboard that didn't survive testing them.
