qcacld-3.0: Avoid SAP bw downgrade when link switch is in progress

Currently, SAP bw gets downgraded(from 320 MHz to 160 MHz) when
link connect starts on a channel which causes DBS/SBS.

But SAP is not aware of the link that can cause DBS/SBS if it is
inactive as corresponding entry is not present in driver policy
mgr table. When link switch is triggered to a channel which
causes SMM to DBS/SBS hw_mode, SAP bw update algo gets triggered
as there is a new connect which causes split-phy mode. SAP bw
update algorithm need not be triggered upon link switch start and
can be triggered post link switch to avoid interrupting link
switch.

Currently, it doesn't differentiate between user connect request
and link switch connect request. Add a check and avoid SAP bw
update trigger link switch cases. Evaluate the links posts
connection and trigger bw update if needed.
