s390/uaccess: fix compile error
Compiling with e.g MARCH=z900 results in compile errors:
arch/s390/lib/uaccess.c: In function 'copy_from_user_mvcos':
>> arch/s390/lib/uaccess.c:65:15: error: variable 'spec' has initializer but incomplete type
65 | union oac spec = {
Therefore make definition of union oac visible for all MARCHs.
