A change to the generic scatterlist code caused a conflict with
the rtsx card reader driver:
In file included from drivers/misc/cardreader/rtsx_pcr.c:32:
include/linux/rtsx_pci.h:40: error: "SG_END" redefined [-Werror]
This changes one instance of the driver to prefix SG_END and
related constants.
Fixes: 723fbf563a6a ("lib/scatterlist: Add SG_CHAIN and SG_END macros for LSB
encodings")
