qcacld-3.0: Update only positive nss values from BDF

Browse source 
If the FW doesn't send the ext service ready event, and
thus the host does not get the max chainmask that both
the macs can support, the host still updates the ini
with the minimum of the host, and FW config, which can
lead to functional issues in connection, and scan.

Fix is to honour the setting only if the FW sends a non
zero positive chainmask for both macs.
