[PATCH] brcmsmac: disable power-save related functions

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

This patch fixes a regression introduced by:

  commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2
  Author: Hauke Mehrtens <hauke@hauke-m.de>
  Date:   Sun Mar 24 01:45:52 2013 +0100

      brcmsmac: remove brcms_bss_cfg->associated

The regression behaviour is described in:

http://www.spinics.net/lists/linux-wireless/msg107474.html

Before the mentioned commit the return value of
the function brcms_c_ps_allowed() was always false,
which is desired behaviour as power-save is not
supported at the moment. Therefor, the function is
changed to just return false instead of simply
reverting the mentioned commit.

Sorry, John

Hope the revised commit message has all the needed
information now. Without this patch brcmsmac is
useless for anyone using it in station mode.
