qcacld-3.0: Validate session id in SME

As part of cds connection in progress validation
check, CDS is accessing the session id from an
adapter which is just created and initialized with
an invalid sessionid. CDS passes the invalid session
id to SME. SME is trying to access global structure
with the same session id and triggered the crash.

Add a session id validation check in SME before
accessing the global mac structure.
