[PATCH] KVM: arm64: Stop the hyp trace clock worker on disable

[Fuad Tabba <fuad.tabba@linux.dev>]

When disabling, hyp_trace_clock_enable() cancels the clock work but then
falls through into the enable path, which re-schedules it and marks the
clock running again, so the worker never stops. Return once the work is
cancelled.
