[PATCH] 2.5.30 scsi_scan.c cleanup/rewrite

Hi -

Attached is cleanup/rewrite patch for scsi_scan.c against 2.5.30.

The only functional change is adding support for BFLAGS_LARGELUN,
it was defined before, but not used, otherwise the code should be
the functional equivalent of the pre-patch version.

The unused BFLAGS_NODISK was removed.

Tested with:

qla2300, v6 beta drivers modified for 2.5.x, with FCP switch attached
	IBM 3542 (multi-LUN FC disk array, supports REPORT LUN)
	SEAGATE ST118273 (FC disk drive)

serveRAID (ips driver, boot device)

AIC Adaptec 7896 with IBM-PSG ST318203LC (boot disk)

ISP1020 (qlogicisp driver) with Quantum DLT7000 tape drive attached

There's a bug for adapters with multiple channels (like the ServeRAID
with ips driver) not being properly scanned - it scans channel 0 again
rather than going to the next channel - patch on top of the original
patch:
