wifi: rtlwifi: rtl8821ae: Fix media status report

mainline inclusion
from mainline-v6.14-rc1
category: bugfix

RTL8821AE is stuck transmitting at the lowest rate allowed by the rate
mask. This is because the firmware doesn't know the device is connected
to a network.

Fix the macros SET_H2CCMD_MSRRPT_PARM_OPMODE and
SET_H2CCMD_MSRRPT_PARM_MACID_IND to work on the first byte of __cmd,
not the second. Now the firmware is correctly notified when the device
is connected to a network and it activates the rate control.
