s390/xor: Fix xor_xc_5() inline assembly
commit 5f25805303e201f3afaff0a90f7c7ce257468704 upstream.
xor_xc_5() contains a larl 1,2f that is not used by the asm and is not
declared as a clobber. This can corrupt a compiler-allocated value in %r1
and lead to miscompilation. Remove the instruction.
Fixes: 745600ed6965 ("s390/lib: Use exrl instead of ex in xor functions")
