qcacld-3.0: Change WMI force mode for ML link switch case

Browse Source 
Currently, to switch links from link A to link B, Host sends
two back-to-back WMI commands to FW, by setting link B force
active and link A force inactive respectively with force
mode MLO_LINK_FORCE_MODE_ACTIVE/MLO_LINK_FORCE_MODE_INACTIVE
but if association is in EMLSR mode, FW considers the first
WMI to set link B active (when link A is already set active)
to be a trigger to enter EMLSR mode and sends OMN frame as
part of it. To avoid this, Host has to send a single WMI
with force mode MLO_LINK_FORCE_MODE_ACTIVE_INACTIVE and
include both active and inactive vdev bitmaps within the
same command to clearly indicate the link switch.
