[PATCH] wifi: rtw89: fix AP mode authentication transmission failed

[Ping-Ke Shih]

From: Po-Hao Huang <phhuang@realtek.com>

For some ICs, packets can't be sent correctly without initializing
CMAC table first. Previous flow do this initialization after
associated, results in authentication response fails to transmit.
Move the initialization up front to a proper place to solve this.
