Drivers: hv: vmbus: Remove the undesired put_cpu_ptr() in hv_synic_cleanup()

commit a0033bd1eae4650b69be07c17cb87393da584563 upstream.

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

Fixes: 37cdd991 ("vmbus: put related per-cpu variable together")
