[PATCH] lk 2.5.3 scsi generic (sg) driver

In lk 2.5.3 the sg driver tries to set up both address
and page+offset in scatterlist entries. Unfortunately
asm-i386/pci.h's pci_map_sg() contains this check:

if (sg[i].address && sg[i].page)
BUG();

which kills that strategy when the sym53c8xx driver
uses pci_map_sg(). This patch has been posted earlier
for lk 2.5.3-pre5 and is still required for lk 2.5.3
