[SCSI] fix CONFIG_SCSI_WAIT_SCAN=m
CONFIG_MODULES=y CONFIG_SCSI=y CONFIG_SCSI_SCAN_ASYNC=y CONFIG_SCSI_WAIT_SCAN=m 2.6.21-rc5-mm2 VFS panics unable to find my root on /dev/sda2, but boots okay if I change drivers/scsi/Kconfig to "default y" instead of "default m" for SCSI_WAIT_SCAN. Make sure there's a late_initcall to scsi_complete_async_scans when it's built in, so a monolithic SCSI_SCAN_ASYNC kernel can rely on the scans being completed before trying to mount root, even if they're slow.
