MIPS: KVM: Fix kvm_debug bit-rottage
Fix build errors when DEBUG is defined in arch/mips/kvm/.
- The DEBUG code in kvm_mips_handle_tlbmod() was missing some variables.
- The DEBUG code in kvm_mips_host_tlb_write() was conditional on an
undefined "debug" variable.
- The DEBUG code in kvm_mips_host_tlb_inv() accessed asid_map directly
rather than using kvm_mips_get_user_asid(). Also fixed brace
placement.
