This doesn't look like a sound approach. I think you should keep
'mwifiex_mgmt_stypes' const, because if you're making modifications to
it, then you may break multi-adapter situations. Consider someone loads
this driver with host_mlme_enabled==true, and then later registers a
device with host_mlme_enabled==false. The second adapter will get the
wrong values.
I think 'mwifiex_mgmt_stypes' is small enough you might as well just
make a second copy with the MLME-enabled values, rather than fiddling
with modifying a single copy.
Aside from that:

(Feel free to carry that to a v11, since my only remaining substantial
concerns are with patch 1 I think.)
