[PATCH 1/4] riscv: kvm: vcpu_timer: fix unused variable warnings

[Conor Dooley <mail@xxxxxxxxxxx>]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

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.

Fixes: 8f5cb44b1bae ("RISC-V: KVM: Support sstc extension")
