[SCSI] aacraid: Fix jbod operations scan issues

Browse source 
As JBOD devices (really just Simple Single Drive Volumes exported to
the SCSI channel) are managed, they fail to update correctly when the
driver triggers a SCSI scan. In addition, the ability to change
multiple arrays or JBODs at the same time was resulting in dropped
scans, set up a mechanism to issue a list of single target scans on a
single configuration change notification from the Firmware.

Performed some additional sundry cosmetic code style cleanups.
