sparc: make xchg() into a statement expression
Fix several of the same warning by using a GCC statement expression
(extension):
../arch/sparc/include/asm/cmpxchg_32.h:28:22: warning: value computed is not used [-Wunused-value]
28 | #define xchg(ptr,x) ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr))))
Passes sparc32 allmodconfig with no xchg warnings.
