staging: rts5208: 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/staging/rts5208/rtsx.h:180,
                 from drivers/staging/rts5208/rtsx.c:28:
drivers/staging/rts5208/rtsx_chip.h:343: 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")
