Currently, an incorrect TID value gets populated in the monitor status Rx
path due to an incorrect bitmap value given to the ffs() built-in helper
function. Therefore, avoid the decrement and directly provide the TID
bitmap to the ffs() built-in helper function for the correct TID update
in the monitor status Rx path.
