Subject: mac80211_hwsim: don't use WQ_MEM_RECLAIM

From: Johannes Berg <[email protected]>

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.
