Johannes Berg 0a28f53936 nl80211: fix sched scan netlink socket owner destruction
commit 753aacfd2e95df6a0caf23c03dc309020765bea9 upstream.

A single netlink socket might own multiple interfaces *and* a
scheduled scan request (which might belong to another interface),
so when it goes away both may need to be destroyed.

Remove the schedule_scan_stop indirection to fix this - it's only
needed for interface destruction because of the way this works
right now, with a single work taking care of all interfaces.

Fixes: 93a1e86ce10e4 ("nl80211: Stop scheduled scan if netlink client disappears")
