qcacld-3.0: Add reason codes for internal disconnections

Currently, host driver sends disconnect reason code as UNSPECIFIED
to kernel in most of the disconnection scenarios. Correct the same
to send proper reason code received from peer in case of peer
initiated disconnections.
Introduce new reason codes for internal disconnections and assign
proper reason code for each possible disconnect scenario.
