Subject: [PATCH 4.19 121/267] brcmfmac: fix wrong location to get firmware feature

From: Jaehoon Chung <jh80.chung@...sung.com>

[ Upstream commit c57673852062428cdeabdd6501ac8b8e4c302067 ]

sup_wpa feature is getting after setting feature_disable flag.
If firmware is supported sup_wpa feature,  it's always enabled
regardless of feature_disable flag.
