qcacld-3.0: Handle concurrency with new EMLSR connection

Currently, if there is a legacy connection and a new STA
connection comes up with EMLSR capability, Host does not
advertise EML caps in assoc request. But there is no support
to enable EMLSR mode if the legacy connection goes away.
Thus, add support to handle this concurrency scenario as
follows
1) Host should advertise EML support capability in assoc
request.
2) After association is complete, force disable one of the
EMLSR links.
3) Once the legacy connection goes down, re-enable the
disabled link.
