ARM: KVM: fix KVM_CAP_ARM_SET_DEVICE_ADDR reporting

Commit 3401d546 (KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR
ioctl) added support for the KVM_CAP_ARM_SET_DEVICE_ADDR capability,
but failed to add a break in the relevant case statement, returning
the number of CPUs instead.

Luckilly enough, the CONFIG_NR_CPUS=0 patch hasn't been merged yet
(https://lkml.org/lkml/diff/2012/3/31/131/1

), so the bug wasn't
noticed.

Just give it a break!
