[SCSI] aacraid: Fix jbod operations scan issues
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.
