wifi: iwlwifi: add support for a wiphy_work rx handler
The wiphy_work infra ensures that the entire worker will run
with the wiphy mutex. It is useful to have RX handlers
running as a wiphy_work, when we don't want the handler to
run in parallel with mac80211 work (to avoid races).
For example - BT notification can disable eSR starting from the next
patch.
In ieee80211_set_active_links we first check that eSR is
allowed, (drv_can_activate_links) and then activate it.
If the BT notif was received after drv_can_activate_links
(which returned true), and before the activation - eSR will be
activated when it shouldn't.
If BT notif is handled with the wiphy mutex, it can't run in
parallel to ieee80211_set_active_links, which also holds that
mutex.
Add the necessary infrastructure here, for use in the next commit.
