s390/uaccess: add missing earlyclobber annotations to __clear_user()
Add missing earlyclobber annotation to size, to, and tmp2 operands of the
__clear_user() inline assembly since they are modified or written to before
the last usage of all input operands. This can lead to incorrect register
allocation for the inline assembly.
Fixes: 6c2a9e6df604 ("[S390] Use alternative user-copy operations for new hardware.")
