openrisc: xchg: fix `computed is not used` warning
When building allmodconfig this warning shows.
fs/ocfs2/file.c: In function 'ocfs2_file_write_iter':
./arch/openrisc/include/asm/cmpxchg.h:81:3: warning: value computed is
not used [-Wunused-value]
((typeof(*(ptr)))__xchg((unsigned long)(with), (ptr), sizeof(*(ptr))))
^
Applying the same patch logic that was done to the cmpxchg macro.
