[PATCH v2] ath10k: Use station's current operating mode from assoc request

[Vivek Natarajan]

The current number of spatial streams used by the client is advertised
as a separate IE in assoc request. Use this information to set
the NSS operating mode.

Fixes: 45c9abc059fa ("ath10k: implement more versatile set_bitrate_mask").
