From: Chung-Hsien Hsu <stanley.hsu@cypress.com>

An incorrect value of use_fwsup is set for 4-way handshake offload for
WPA//WPA2-PSK, caused by commit 3b1e0a7bdfee ("brcmfmac: add support for
SAE authentication offload"). It results in missing bit
BRCMF_VIF_STATUS_EAP_SUCCESS set in brcmf_is_linkup() and causes the
failure. This patch correct the value for the case.

Also setting bit BRCMF_VIF_STATUS_EAP_SUCCESS for SAE offload case in
brcmf_is_linkup() to fix SAE offload failure.

Fixes: 3b1e0a7bdfee ("brcmfmac: add support for SAE authentication
offload")

Fixes line needs to be in one line. I can fix that during commit, no
need to resend because of this.

Thanks a lot for fixing it. We'll use one line going forward.
