s390/compat: fix PSW32_USER_BITS definition
commit 075dfd82102d2048e43e1cbf48d558d915c50072 upstream.
PSW32_USER_BITS should define the primary address space for user space
instead of the home address space.
Symptom of this bug is that gdb doesn't work in compat mode.
The bug was introduced with e258d719ff28 "s390/uaccess: always run the kernel
in home space" and f26946d7ecad "s390/compat: make psw32_user_bits a constant
value again".
