wifi: rtw89: mlo: fix missing TX null-data 1 during link switch

Browse Source 
Fix missing null-data 1 when switching links. The FW should send a
null-data 1 to notify AP before disabling the old link. Adjust the
position of the H2C rtw89_fw_h2c_mlo_link_cfg to ensure proper FW
behavior during link transition.
