riscv: kvm: vcpu_timer: fix unused variable warnings

Browse Source 
In two places, csr is set but never used:

arch/riscv/kvm/vcpu_timer.c:302:23: warning: variable 'csr' set but not used [-Wunused-but-set-variable]
        struct kvm_vcpu_csr *csr;
                             ^
arch/riscv/kvm/vcpu_timer.c:327:23: warning: variable 'csr' set but not used [-Wunused-but-set-variable]
        struct kvm_vcpu_csr *csr;
                             ^

Remove the variable.
