LoongArch: KVM: Do not restart SW timer when it is expired

LoongArch VCPUs have their own separate HW timers. SW timer is to wake
up blocked vcpu thread, rather than HW timer emulation. When blocking
vcpu scheduled out, SW timer is used to wakeup blocked vcpu thread and
injects timer interrupt. It does not care about whether guest timer is
in period mode or oneshot mode, and SW timer needs not to be restarted
since vcpu has been woken.

This patch does not restart SW timer when it is expired.
