[][MAC80211][WiFi6][mt76][not send RTS before sending BSRP]

[Description]
Fix to not send an RTS before sending BSRP.

For HE-4.49.1 BSRP in UL OFDMA test case, if AP sends RTS before sending
BSRP frame, this will cause some stations to not send a qos_null packet
in response to our BSRP. With this change, it sends MURU_SET_PROT_FRAME_THR
mcu cmd to instruct us not to send RTS before sending BSRP.

This change only affects cetification test cases with CAPI command as
ap_set_wireless,OFDMA.
