This is another one you can't do: all headers in UAPI are exports to
userspace and the definitions constitute an ABI.  If you simply do a
rename, every userspace program that uses the current definition will
immediately break on compile.  You could add HASH_ALGO_SM3, but you
can't remove HASH_ALGO_SM3_256
