wifi: cfg80211: ignore link disabled flag from userspace
When the AP has an advertised TID to Link Mapping (TTLM) it shall
include the element in the association response. As such, when this
element is present it needs to be used for the currently dormant links.
See Draft P802.11REVmf_D1.0 section 35.3.7.2.3 ("Negotiation of TTLM")
for the details. The flag is also not usable in case userspace wants to
specify a negotiated TTLM during association.
Note that for the link reconfiguration case, mac80211 did not use the
information. Draft P802.11REVmf_D1.0 states in section 35.3.6.4 ("Link
reconfiguration to the setup links) that we "shall operate with all the
TIDs mapped to the newly added links ..."
All this means that the flag is not needed. The implementation should
parse the information from the association response.
