The current code is poorly structured and potentially leads to multiple
config space reads when one is sufficient. Also the UNPLUG_ALL_IDE_DISKS
flag is mis-named since it also results in SCSI disks being unplugged.
This patch renames the flag and re-structures the code to be more
efficient, and readable.
