misc: rtsx: rename SG_END macro

Browse Source 
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: 723fbf563a ("lib/scatterlist: Add SG_CHAIN and SG_END macros for LSB encodings")
