LoongArch: KVM: Reload guest CSR registers after sleep
On host, the HW guest CSR registers are lost after suspend and resume
operation. Since last_vcpu of boot CPU still records latest vCPU pointer
so that the guest CSR register skips to reload when boot CPU resumes and
vCPU is scheduled.
Here last_vcpu is cleared so that guest CSR registers will reload from
scheduled vCPU context after suspend and resume.
