[PATCH 4.19 005/287] wifi: mac80211_hwsim: add back erroneously removed cast

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit 58b6259d820d63c2adf1c7541b54cce5a2ae6073 upstream.

The robots report that we're now casting to a differently
sized integer, which is correct, and the previous patch
had erroneously removed it.
