Jens Freimann 4756129f7d KVM: s390: fix get_all_floating_irqs 
commit 94aa033efc upstream.

This fixes a bug introduced with commit c05c4186bb ("KVM: s390:
add floating irq controller").

get_all_floating_irqs() does copy_to_user() while holding
a spin lock. Let's fix this by filling a temporary buffer
first and copy it to userspace after giving up the lock.
