[PATCH 3.19 078/101] brcmfmac: disable MBSS feature for BCM43362

[Greg Kroah-Hartman]

3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arend van Spriel <arend@xxxxxxxxxxxx>

commit f93a25b38cbd840f26c9fd2dd8a6611a57b259b7 upstream.

The BCM43362 firmware falsely reports it is capable of providing
MBSS. As a result AP mode no longer works for this device. Therefor
disable MBSS in the driver for this chipset.
