qcacld-3.0: Skip num_vdev-1 if disable NAN feature

Currently if disable NAN support in host and fw, max vdev will still
decrease 1, which make it unable to support 4 SAP currency case.

Fix it by checking WMI_SERVICE_NAN capability, if don't have to support
NAN feature, skip reserve vdev for NAN in host.
