s390: Keep I/O interrupts enabled for all iscs.

do_io_interrupt() would stop scanning further iscs if it found
an I/O interrupt it could inject. This might cause the pending
interrupt indication for I/O interrupts to be reset although there
might be queued I/O interrupts for subsequent iscs....

s390: Fix handling of iscs.

There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.

Unfortunately, we have treated to I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as...

s390x: silence warning from GCC on uninitialized values

As best I can tell, this is a false positive.

target-s390x: Fix wrong comparison in interrupt handling

gcc with -Wextra complains about an ordered pointer comparison:

target-s390x/helper.c:660:27: warning:
ordered comparison of pointer with integer zero [-Wextra]

Obviously the index was missing in the code....

target-s390x: Fix debug output (continued)

Since its introduction in d5a439645a5a70fed5431318c3bce9dc2caa950f
(s390x: helper functions for system emulation) the variable name was
raddr. Fix this.

target-s390x: Fix debug output

Commit 71e470886fb6092504503a5fe41092ace71c096c (target-s390x: fix
style) renamed the cpu_s390x_handle_mmu_fault() argument from _vaddr to
orig_vaddr. Update the debug output code.

target-s390x: Clean up cpu_inject_*() signatures

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,...

target-s390x: Pass S390CPU to s390_{add, del}_running_cpu()

This prepares for moving the halted field to CPUState.
Most call sites can already supply S390CPU, for some env becomes unused.
