Subject: [PATCH] rtw88: Fix incorrect beamformee role setting

From: Tzu-En Huang <[email protected]>

In associating and configuring beamformee, bfee->role is not
correctly set before rtw_chip_ops::config_bfee().
Fix it by setting it correctly.

Fixes: 0bd9557341b7 ("rtw88: Enable 802.11ac beamformee support")
