[PATCH 4.15 006/146] mac80211_hwsim: dont use WQ_MEM_RECLAIM

[Greg Kroah-Hartman]

4.15-stable review patch.  If anyone has any objections, please let me know.

commit ce162bfbc0b601841886965baba14877127c7c7c upstream.

We're obviously not part of a memory reclaim path, so don't set the flag.

This also causes a warning in check_flush_dependency() since we end up
in a code path that flushes a non-reclaim workqueue, and we shouldn't do
that if we were really part of reclaim.
