When inserting a link STA, make sure it doesn't exist first
and add lockdep assertions that we cannot modify the hash
table without holding the sta_mtx, so this check is really
correct.
Also return without hashing if the driver failed, and warn
if the hashing fails, which shouldn't happen due to the
check described above.

Fixes: ba6ddab94fc6 ("wifi: mac80211: maintain link-sta hash table")
