rxrpc: Fix missing security check on incoming calls
Fix rxrpc_new_incoming_call() to check that we have a suitable service key
available for the combination of service ID and security class of a new
incoming call - and to reject calls for which we don't.
This causes an assertion like the following to appear:
rxrpc: Assertion failed - 6(0x6) == 12(0xc) is false
kernel BUG at net/rxrpc/call_object.c:456!
Where call->state is RXRPC_CALL_SERVER_SECURING (6) rather than
RXRPC_CALL_COMPLETE (12).
Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code")
