[PATCH] s390: in_interrupt vs. in_atomic

The condition for no context in do_exception checks for hard and soft
interrupts by using in_interrupt() but not for preemption.  This is bad for
the users of __copy_from/to_user_inatomic because the fault handler might call
schedule although the preemption count is != 0.  Use in_atomic() instead
in_interrupt().
