qcacld-3.0: Fix incorrect value of Rx Nss in operating mode field

Browse source 
Fix the incorrect value of receive spatial streams added for use
in operating mode field. The Operating Mode field is present in
the Operating Mode Notification frame and Operating Mode
Notification element. These are used to notify STAs that the
transmitting STA is changing its operating channel width, the
maximum number of spatial streams it can receive, or both.

As per the 802.11ac spec:
- If the Rx NSS Type subfield is 0, indicates the maximum number
of spatial streams that the STA can receive.
- If the Rx NSS Type subfield is 1, indicates the maximum number of
spatial streams that the STA can receive as a beamformee in an SU
PPDU using a beamforming steering matrix derived from a VHT
Compressed Beamforming report with Feedback Type subfield
indicating MU in the corresponding VHT Compressed Beamforming
frame sent by the STA.

Set to 0 for Nss = 1
Set to 1 for Nss = 2
...
Set to 7 for Nss = 8
