qcacld-3.0: Remove duplicate logic to move to SMM from STA connect

In csr_roam_connect, driver check and move to DBS before the connect
is requested if required and once connection is completed, it check
if SMM can be achieved depending on the channel it connected to or
if it failed to connect.

Thus there is no need to check before connection is completed
if SMM is required as driver is not aware of the channel in which
STA will end up connected.

Thus remove the duplicate logic to move to SMM from STA connect.
