[PATCH v3] rtw88: Fix incorrect beamformee role setting

[PATCH v3] rtw88: Fix incorrect beamformee role setting

[yhchuang]

From: Tzu-En Huang <tehuang@realtek.com>

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

v1 -> v2
  * cannot put bfee->role = RTW_BFEE_NONE after out_unlock
    put it enclosed by else

v2 -> v3
  * remove unnecessary 'else' statement
