commit 8929f95b2b587791a7dcd04cc91520194a76d3a6 upstream.
This reverts commit c46bfba1337d ("connector: Fix proc_event_num_listeners
count not cleared").
It is not accurate to reset proc_event_num_listeners according to
cn_netlink_send_mult() return value -ESRCH.
In the case of stress-ng netlink-proc, -ESRCH will always be returned,
because netlink_broadcast_filtered will return -ESRCH,
which may cause stress-ng netlink-proc performance degradation.
