[PATCH 7/8] brcmfmac: not set mbss in vif if firmware does not support MBSS

[Soeren Moch <smoch@web.de>]

From: Wright Feng <wright.feng@cypress.com>

With RSDB mode, FMAC and firmware are able to create 2 or more AP,
so we should not set mbss in vif structure if firmware does not
support MBSS feature.
