KVM: arm64: guest: fix kernel-doc warnings

Fix multiple function parameter descriptions to prevent warnings:

guest.c:718: warning: Function parameter or struct member 'vcpu' not described in 'kvm_arm_num_regs'
guest.c:736: warning: Function parameter or struct member 'vcpu' not described in 'kvm_arm_copy_reg_indices'
guest.c:736: warning: Function parameter or struct member 'uindices' not described in 'kvm_arm_copy_reg_indices'
arch/arm64/kvm/guest.c:915: warning: Excess function parameter 'kvm' description in 'kvm_arch_vcpu_ioctl_set_guest_debug'
arch/arm64/kvm/guest.c:915: warning: Excess function parameter 'kvm_guest_debug' description in 'kvm_arch_vcpu_ioctl_set_guest_debug'
