[PATCH for 3.10 07/16] brcmfmac: On bus flow control use fw signalling or netif.

["Arend van Spriel" <arend@broadcom.com>]

From: Hante Meuleman <meuleman@broadcom.com>

Currently on a bus flow control both fws is informed and netif queue
gets closed. In case of fw signalling enabled, let the flow control
be handled by fw signalling only.
