Subject: [PATCH] KVM: MIPS/VZ: Fix build error caused by 'kvm_run' cleanup

Commit c34b26b98caca48ec9ee9 ("KVM: MIPS: clean up redundant 'kvm_run'
parameters") remove the 'kvm_run' parameter in kvm_vz_gpsi_lwc2.

The following build error:

arch/mips/kvm/vz.c: In function ‘kvm_trap_vz_handle_gpsi’:
arch/mips/kvm/vz.c:1243:43: error: ‘run’ undeclared (first use in this function)
   er = kvm_vz_gpsi_lwc2(inst, opc, cause, run, vcpu);
                                           ^~~
arch/mips/kvm/vz.c:1243:43: note: each undeclared identifier is reported only 
 once for each function it appears in
