Currently with MLO changes, RNR formation for co-location or MLO
was not working as expected. Hence make it work as per the
expectation.
For example, during co-location, if the BSS is also its ML partner
then there is no need to include a separate TBTT for it.
Also, during co-location, if the BSS is not its partner but it is
ML capable, then the TBTT length should be 16 bytes and it should
include the MLD Parameters for it in the RNR.
During co-location, for a given Neighbor AP (operating on a given
channel and op-class) if it has BSSes which are ML capable as well
as BSSes which are not, then there should be two Neighbor AP Info
present. One indicating TBTT length as 13 bytes and one indicating
TBTT info length as 16 bytes.
