Johannes Berg 8f4fa08762 wifi: mac80211: use monitor sdata with driver only if desired 
In commit 0d9c2beed1 ("wifi: mac80211: fix monitor channel
with chanctx emulation") I changed mac80211 to always have an
internal monitor_sdata to have something to have the chanctx
bound to.

However, if the driver didn't also have the WANT_MONITOR flag
this would cause mac80211 to allocate it without telling the
driver (which was intentional) but also use it for later APIs
to the driver without it ever having known about it which was
_not_ intentional.

Check through the code and only use the monitor_sdata in the
relevant places (TX, MU-MIMO follow settings, TX power, and
interface iteration) when the WANT_MONITOR flag is set.
