target/arm: Initialize debug capabilities only once

Browse source 
kvm_arm_init_debug() used to be called several times on a SMP system as
kvm_arch_init_vcpu() calls it. Move the call to kvm_arch_init() to make
sure it will be called only once; otherwise it will overwrite pointers
to memory allocated with the previous call and leak it.

Fixes: e4482ab7e3 ("target-arm: kvm - add support for HW assisted debug")
