wifi: mac80211: make monitor link info check more specific

Verify that only one of the permitted change flags is set when changing
the link of a monitor interface. Before the WARN_ON_ONCE would accept
anything if mu_mimo_owner was set.

Also, split out the mu_mimo_owner flag and enable it for all interface
types. The option is set during association when VHT is available and it
is not expected that any configuration of the MU groups is done without
it being set.
