wifi: iwlwifi: mld: cancel wiphy work before freeing wiphy

Browse Source 
When we fail to load the fw during op-mode start, we purge the list
of the async handlers but we don't cancel the work.
Same when we stop the op-mode.

Before freeing wiphy, we need to cancel/flush any pending wiphy work,
otherwise the work will fire with a freed memory.
cfg80211 will do it anyway, but it will warn.

Cancel the work in those cases.
