qcacld-3.0: Retain connection if only short/long preamble caps changes

Currently, driver issues disconnection if only short/long
preamble caps changes occur. This results in frequent disconnections.
Firmware anyway doesn't take care of short/long preamble peer
capability so this shouldn't cause any side effect as most of the
peers today support short preamble.

Fix is to prevent disconnection if only short/long preamble caps
change occurs.
