Ilya Leoshkevich 1b301f5f28 s390/irqflags: do not instrument arch_local_irq_*() with KMSAN 
Lockdep generates the following false positives with KMSAN on s390x:

[    6.063666] DEBUG_LOCKS_WARN_ON(lockdep_hardirqs_enabled())
[         ...]
[    6.577050] Call Trace:
[    6.619637]  [<000000000690d2de>] check_flags+0x1fe/0x210

[    6.927454]  [<0000000000100036>] startup_continue+0x36/0x40

Between trace_hardirqs_on() and `stosm __mask, 3` lockdep thinks that
interrupts are on, but on the CPU they are still off.  KMSAN
instrumentation takes spinlocks, giving lockdep a chance to see and
complain about this discrepancy.

KMSAN instrumentation is inserted in order to poison the __mask variable. 
Disable instrumentation in the respective functions.  They are very small
and it's easy to see that no important metadata updates are lost because
of this.
