Subject: Drivers: hv: vmbus: Remove the undesired put_cpu_ptr() in hv_synic_cleanup()
Git-commit: a0033bd1eae4650b69be07c17cb87393da584563

With CONFIG_DEBUG_PREEMPT=y, the put_cpu_ptr() triggers an underflow
warning in preempt_count_sub().

Fixes: 37cdd991fac8 ("vmbus: put related per-cpu variable together")
