csky: fix csky_cmpxchg_fixup not working
In the csky_cmpxchg_fixup function, it is incorrect to use the global
variable csky_cmpxchg_stw to determine the address where the exception
occurred.The global variable csky_cmpxchg_stw stores the opcode at the
time of the exception, while &csky_cmpxchg_stw shows the address where
the exception occurred.
