2.3.44: CONFIG_Sx_EXTRA_DEVS breaks with some configs

From: Tim Waugh (tim@cyberelk.demon.co.uk)

In my .config I have:

# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
# CONFIG_CHR_DEV_ST is not set
CONFIG_ST_EXTRA_DEVS=2
# CONFIG_BLK_DEV_SR is not set
CONFIG_CHR_DEV_SG=m

..so I needed this patch to get sg.c to compile. There must be a better
way. ;-)

Tim.
